Eighty rescue workers and 18 tonnes of supplies have arrived from Switzerland, according to Venezuela's state broadcaster.

They arrived in the early hours of Friday morning, and the team also includes eight search dogs, reports Venezolana de Televisión.

It adds that Switzerland was "one of the first" countries to offer an emergency response after the earthquakes.

Foreign nationals are among those confirmed to have died, although as with much of the information coming out of the country since Wednesday's earthquakes, we still do not know the full picture - and search efforts are continuing.

The Spanish foreign minister, José Manuel Albares, says the number of Spanish nationals confirmed dead has risen to three, and 99 are now missing.

A Brazilian man and a Brazilian woman have died, according to the country's foreign ministry.

Chinese state media cites the Chinese embassy in Caracas as saying last night that two Chinese nationals had been confirmed dead.

An Italian-Venezuelan has been confirmed dead, Italian media reports, citing the foreign ministry, which adds there is a large Italian community in Venezuela and it is "very difficult" at this time to estimate how many are missing.

Nine Portuguese nationals have died, the AFP news agency reports, citing the country's foreign ministry.

A spokesperson for the the International Search and Rescue Dog Organisation (IRO) tells the BBC that six teams of dogs and handlers are heading to Venezuela to help find survivors.

Nicola Puchelt explains that the first 72 hours of an operation are crucial but insists there is "always hope" of finding people alive after several days.

She explains that two dogs are used in each search, the first barks to signal that a person is in the rubble, a second dog will then be sent to confirm the finding before the site is excavated.

Puchelt pays tribute to the highly trained dogs and their handlers who she says need "very strong physical and emotional strength".

Spain’s foreign ministry has confirmed two Spanish nationals have died in the earthquake, while another 80 are missing.

According to Spanish media, citing family sources, one of the victims with Spanish nationality is Alazne Solabarrieta Lecea, a 65-year-old who was born in Caracas.

Her grandfather was José María Solabarrieta, the mayor of the Basque town of Ondarroa during Spain’s Second Republic and who later went into exile in Venezuela, Spanish media reports.

Her husband, Luis María Olalde Quintela, described by Spanish media as a former member of the Basque separatist group ETA who fled to Venezuela in the late 1970s, is reportedly recovering in hospital after being injured in the earthquake.

He is named in the Civil Guard’s database as someone the judiciary is attempting to bring to justice.

The Spanish authorities have set up telephone help lines in Spain and Venezuela for its nationals who are looking for loved ones.

Spain has sent a military aircraft to Venezuela with personnel who will help with rescue efforts.

The Spanish foreign ministry told the BBC it could not at this time confirm the identities of those killed.

Satellite photos show scale of damage in La Guairapublished at 10:43 BST

New satellite photos reveal the extent of the damage to La Guaira, more than 100 miles (160km) from the epicentres of the devastating double earthquakes.

The images were captured by the US spacial intelligence firm Vantor and show some of the worst-hit parts of the port city just north of Venezuela’s capital Caracas.

One photo shows a cluster of six buildings flattened, most of them were high-rise apartment complexes with outdoor pools. Some of the surrounding roads have become blocked with debris and collapsed buildings.

Another image also shows how multi-storey blocks which once overlooked the Caribbean Sea have been reduced to rubble.

It's currently 05:20 in Caracas and not yet light.

Rescue teams have continued their searches through the night. You can see some of the latest pictures below.

The 7.2-magnitude and 7.5-magnitude quakes hit less than a minute apart at around 18:00 local time (23:00 BST) on Wednesday, according to the US Geological Survey (USGS).

The second was the strongest earthquake to hit the country since 1900.

The so-called doublet sequence of earthquakes is different to the typical scenario, where a larger quake is followed by much smaller aftershocks.

Both were very shallow at less than 30km below ground, potentially adding to the damage. We have seen footage of the moment the earthquake shook a BBC journalist's home in Caracas.

An earthquake occurs when two parts of the Earth suddenly move past each other which releases a lot of energy. When this energy reaches the surface it causes the ground to shake.

The closer it is to the surface, typically the more shaking and potential damage.

US Southern Command (Southcom), which oversees US forces activity in south America, says Major General Kevin Jarrard has arrived in Caracas to oversee the Department of Defence's support for relief efforts.

In a post on social media, it says it will help "support the rapid, life-saving movement of response personnel, equipment, and humanitarian assistance into affected areas".

The US set out more details yesterday about how it plans to support Venezuela after the earthquakes.

Graciela Mora was conscious as she was pulled from the rubble of a collapsed building in La Guaira by emergency workers and volunteers.

"When the earthquake started, I clung as tightly as I could to the doorframe," she says, "so tightly that I broke my finger."

She was rescued with injuries, including a broken finger, but a friend she was with at the time died.

She told the Associated Press that she held her friend's hand while waiting to be rescued so she would not have to die alone.

Speaking to camera moments after her rescue, and while still on a stretcher, she says she held onto the doorframe "until all the floors collapsed".

"And then I saw her hand like that and grabbed it," she says.

We've just reported on a doctor who has travelled from Caracas to La Guaira who describes the healthcare system there as being "completely overwhelmed" after the quakes.

Last night, another Venezuelan doctor, Pedro Javier Fernandez, a member of the medical group Medicos Unidos Venezuela, told the BBC the challenging economic and humanitarian circumstances in the country that preceded the earthquakes makes it even harder to respond.

"The problem is not only this is a natural tragedy, but we have to realise and we have to remember that Venezuela is in the context of a humanitarian, complex emergency," he says.

"All our hospitals lack supplies, lack medicines, we are not able to provide medical attention to our people in a normal day. Now with this tragedy, the emergency is even bigger and it's more difficult to face than in other countries."

Dr Franklin Rodriguez has travelled to the region of La Guaira - which has been badly affected by the quakes - from the capital Caracas where he usually works.

He tells Radio 4's Today programme that he and his fellow medics are facing a desperate situation.

Dr Rodriguez describes the system as being in complete collapse with the two main hospitals in the state "completely overwhelmed".

He says: "There is a critical lack of medicine and medical supplies. Medical facilities do not have the capacity to handle the massive volume of people, and many people are still trapped under the rubble."

People in Venezuela have spoken to the BBC about the intensity of the quakes that hit on Wednesday evening:

Juan, a medical student in Caracas told us he has "multiple friends from my university who are missing".

Twenty-year-old Antoan Marín, who lives in the San Agustín neighborhood in Caracas, told BBC Mundo he felt like his house was going to "split in two", and feared he might die.

Manu Quintero, a journalist in Caracus, said that "the world was moving for a long time" when the earthquakes struck, adding that the two quakes felt like "one massive long earthquake".

Wednesday, 18:04 local time (23:04 BST): An earthquake of 7.2 magnitude strikes in the north of Venezuela.

About 39 seconds later: A second earthquake with a 7.5-magnitude strikes, 28km south-east of Yumare, a town in the Yaracuy state. This was the strongest to hit the country since 1900.

A few hours later: Footage emerges of people fleeing through the halls of Maiquetía airport as debris falls in La Guaira state, which closes shortly after. The mayor of Chacao, Gustavo Duque Saez, says 18 people had been rescued alive and more than 500 emergency workers were in Chacao trying to pull out more residents.

23:45 local time (04:45 BST): US President Donald Trump says "two major earthquakes...have left a devastating number of deaths," adding: "Early reports are not good!!!"

Thursday, around 00:50 local time (05:50 BST): Venezuela's acting president, Delcy Rodriguez, reports at least 32 deaths, and more than 700 injured. She says this figure does not include any figures from the state most affected by the earthquakes, La Guaira. These figures are updated through the day.

Throughout Thursday: As rescuers and the army were mobilised to clear debris, aid groups around the world scrambled to deliver help to Venezuela, with the US pledging $150m in assistance.

Rescuers are searching through rubble in Venezuela in a rush to save lives after powerful earthquakes that have killed at least 235 people.

At least 4,300 people have been injured by the 7.2 and 7.5 magnitude quakes that struck on Wednesday evening local time.

In Caracas and La Guaira, people could be heard calling for help under the debris of collapsed buildings.

Jorge Rodríguez, the president of Venezuela's National Assembly, said 250 buildings had been damaged or lost, mostly in La Guaira, where the BBC verified footage of a 10-storey hotel reduced to rubble.

Buildings were also brought down in the capital, Interior Minister Diosdado Cabello said, with Trujillo, Yaracuy, Carabobo, Aragua and Miranda also affected.

A massive search and rescue effort is under way in Venezuela after twin earthquakes devastated the Caracas region, killing more than 100 people and leaving many others injured or trapped under rubble.

What happened

Back-to-back earthquakes - measuring 7.2 and 7.5 - struck northern Venezuela on Wednesday night, killing at least 188 people, injuring more than 1,500, and leveling hundreds of buildings.

"We spent the night in a public square. Most of the neighbours slept in the streets," central Caracas resident Leander Pérez told the BBC. "I have friends with missing relatives."

State media channel Venezolana de Televisión says 157 people are reported missing, though the exact figure is unclear.

Search and rescue operation

Emergency workers are racing to reach people trapped beneath the rubble in Caracas and the state of La Guaira.

The next few hours prove crucial in rescuing survivors.

"I just want to know where my son is," said Dayana Delgado, a La Guaira resident.

Humanitarian crisis and international aid

The destruction could worsen living conditions for millions of Venezuelans in an "already severe" humanitarian crisis, charity Oxfam has warned.

Countries around the world have stepped in to offer financial and logistical support to the emergency response, including the UK, US, Qatar, Mexico, China and Russia.

The Trump administration is deploying military assets and a specialised teamto help search and rescue efforts and also mobilising more than $200m (£151m) in assistance.

We're now pausing our live coverage. You can read more about what is happening in Venezuela here.

A former Obama administration official tells the BBC the earthquakes will test Venezuelan leader Delcy Rodriguez's legitimacy and could "exacerbate" the country's already tenuous political stability.

Rebecca Bill Chavez, former deputy assistant defence secretary for the Western hemisphere under Obama, says if Acting President Rodriguez is able to "marshal the international support that's needed" it could work in her favour, but "it could be a real disaster for her if that doesn't happen".

Chavez added that the Trump administration's shuttering of the US Agency for International Development (USAID) - which traditionally oversees humanitarian support - will be a challenge for the US response.

"This is going to also be a real test about what the dismantling of USAID means, because there is a lot of muscle memory in USAID about how to react to these sorts of natural disasters," she said. "So that is gone."

From Miami to Mexico to Switzerland, aid from around the world is on the way for victims of the earthquakes in Venezuela.

The satellite internet provider Starlink also announced it would offer free service for the next month.

A non-profit rescue group helping evacuate Americans from Venezuela has described a "dangerous and complicated" situation in the areas hit by the twin earthquakes.

One of the biggest challenges to helping people in the country is communications, Bryan Stern, founder of Grey Bull Rescue based in Florida, told the BBC. We've been hearing about telecommunications problems since the earthquakes struck on Wednesday evening.

"Lots of people are hurt and in need, and they literally can't even ask for help," he said. "The people on the ground need everything. They need clothes. They need comms. They need places to live."

Stern's group is also working with other organisations to deliver supplies and is "bringing a full comms package" to the region, but he said his group needs "financial resources" to continue helping with the response.

Spain's World Cup team held a minute of silence at training to honour the victims of Wednesday's earthquakes.

Venezuela is not competing in the Fifa World Cup but many had gathered in the country to watch matches when the twin earthquakes struck.

Besides the players, Spain's Prime Minister Pedro Sanchez has sent a solidarity message to Venezuela.

"Spain is prepared to help," he says in a message before announcing rescue teams are being dispatched to the country.
