A British firefighter helping search and rescue efforts in Venezuela says his team retains "hope" despite the window for finding survivors shrinking.

"There's obviously a lot of devastation, collapsed buildings, houses, you can see homeless people with no places to go... it's shocking to see," says Mark Leeson of West Midlands Fire Service, who has been sent to Venezuela as part of a UK-wide team.

Leeson tells BBC Radio 4's Today programme that his team uses search and rescue dogs trained to only find living survivors. The dogs bark when they pick up a scent before the rescue team is deployed.

He says there is a generally a 96-hour window when rescuers can expect the save most lives following a disaster such as this one, but says "every now and then you will get that miracle rescue".

"You've always got that hope that you can make a difference."

Many Venezuelans have been critical of the government's response to last week's earthquakes, saying equipment and state manpower have been lacking, with many communities undertaking rescue work themselves.

The first 72 hours after a disaster are crucial for finding people - it's now been more than 100 since the earthquakes hit on Wednesday.

One man, Wilber, who said he had lost eight of his relatives, told the BBC on Sunday the state has been a hindrance, not a help.

"The government decided to close the streets," he said, adding it was "making it harder to bring help".

"Yesterday we waited from 6am to 4pm to get a special permission to come here. We wasted hours," he said.

There have been multiple reports of people searching the rubble with their bare hands in an effort to find loved ones.

Over the weekend, a Mexican fireman and disaster assessment specialist told the BBC the situation was "extremely challenging", with the country’s rescue equipment "decades behind international standards".

Similarly, there have been reports that the health system has been overwhelmed by the challenge, with one doctor saying the state struggled to provide healthcare even on a "normal day" before the disaster.

Opposition leaders say the government has mismanaged the economy and public services for years, reducing its capacity to respond. The government itself says rescuers have been deployed and the state is co-ordinating the response.

So far, Venezuelan officials have confirmed that 1,450 people have died following the quakes, however, we do not yet know the actual figure.

Immediately following the two earthquakes, the US Geological Survey's (USGS) estimated the potential fatalities at likely between 10,000 and 100,000.

This is not an exact figure but is calculated based off the size of the quake and the population in the affected area to help emergency responders deploy resources effectively.

The Venezuelan government has not yet provided an estimate of the total fatalities, but with tens of thousands believed to still be missing, the death toll is expected to climb further as rescue operations continue.

A civilian-run missing persons site is reporting that more than 46,000 people remain unreachable by family members.

Among those rescued at the weekend were two 11-year-old boys, who were separately rescued from collapsed buildings within hours of each other on Sunday.

Colombia's National Unit for Disaster Risk Management (UNGRD) pulled 11-year-old boy Moises from under about 3m (9.8ft) of debris.

Reuters reported that a rescuer was overheard on a walkie-talkie saying the young boy was found near his sister and mother, who had both died.

Hours later,interim President Delcy Rodríguezposted a video on X, purportedly showing the rescue of a second 11-year-old boy in the town of Caraballeda.

American and French rescue teams also pulled a man and his teenage son from the rubble in La Guaira.

A French rescuer says they are "extremely weak" and that teams are doing "everything we can to rehydrate them".

At least 1,450 people have died following the two earthquakes that hit Venezuela on Wednesday, according to the latest update from officials.

On Sunday evening, top lawmaker Jorge Rodríguez announced that a further 3,150 have been injured, saying rescuers were now in the "critical hours" to save lives.

He added that 774 buildings have been collapsed or been impacted by the quakes and that a total of 12,721 people have been displaced.

Speaking to foreign rescuers on Sunday evening, interim President Delcy Rodriguez said 33 people had been rescued over the weekend.

Earlier on Sunday, Unicef estimated that 1.8 million people were in need of humanitarian aid following the incident, including 680,000 children.

The United Nations Development programme also estimated the cost of the "direct physical damage" at $6.7bn (£5.1bn), or about 6% of the country's GDP.

Wilker Molaya has been desperately trying to rescue his daughter after the building she was in collapsed in La Guaira during last week's double earthquakes in Venezuela.

"I pulled my daughter halfway out," he tells the Reuters news agency, but adds: "They don't give us any equipment, and we have families there."

Molaya isn't the only one still trying to rescue family from the rubble. Hector Villegas says his ex-wife, his son-in-law's mother and his eldest grandson where inside a building when the quake hit.

"Since that day, we haven't been able to locate their bodies," Villegas says. "I see that rescue efforts are under way and we'll be here waiting."

Mexican Red Cross volunteer Adalberto Pastor says rescuers are now using electronic equipment to locate people after first relying on search dogs.

"We are currently continuing the search using electronic equipment, which allows us to be more certain about the locations that the dog teams may have already detected," Pastor says.

A large part of La Guaira state - one of the worst affected areas - has been reconnected to the power grid, acting President Delcy Rodríguez says.

In an update posted a few hours ago on social media, she says the government has also restored most of the road network there, and is progressively restoring water supplies.

A presidential commission has been set up to assess homes and infrastructure, she says, and a task force has been created to set up temporary shelters.

Planning is also under way for projects to build news housing on short time frames, she says.

Search rescues are ongoing, and the government will not rest until it locates everyone who can be rescued, she says, ending her posts with a message of "hope for all Venezuelans".

As we've been reporting, there is growing anger with the government in Venezuela - with opposition leaders and ordinary Venezuelans accusing it of responding too slowly.

The walls outside hospitals in Caracas are slowly filling up with pictures of the missing.

By the hour, families tack up more photos desperately looking for information about their loved ones.

The morgue in the capital is overwhelmed and as more bodies are brought in there is simply not enough space to store them, even until they can be identified and returned.

Search and rescue operations continue in many areas, and while more relief teams are arriving in the country from different parts of the world every day, there is still an acute shortage of the equipment and manpower required to dig through the rubble.

Anger against the Venezuelan government has been growing, as residents say it isn’t doing enough to help them.
