Search for survivors of twin Venezuela earthquakes enters ‘critical hours’

Rescue crews aren't giving up hope in Venezuela, still searching through the rubble of collapsed buildings

listening for any sign of life five days after twin earthquakes rattled the country

Rescuers miraculously pulled surviving people from the rubble this weekend after they were buried for four days

Acting President Delce Rodriguez says these search and rescue operations will continue

The rescuers say they've entered critical hours to find survivors. Officials say the quakes killed more than 1,400 people, upwards of 3,000 were injured

and nearly 13,000 have been displaced. The death toll is still expected to rise

The country's National Assembly leader said Sunday that 774 buildings had been damaged or destroyed

including 189 that completely collapsed. In La Guayra, the hardest-hit area, officials say rescue efforts are being hampered by civilians

with relief supplies and volunteers. They say the influx of people trying to help is clogging the only highway into the region

leaving many rescue workers stuck in traffic. They're trying to limit those rescue efforts to only those authorized to help

but civilians who are frustrated with the government's disaster response continue to pour in
