The death ‌toll from twin earthquakes that hit Venezuela on June 24 had climbed to at least 1,450 as of June 27 as foreign rescue teams poured into the hardest-hit state of La Guaira.

"We must report that the number of fatalities has reached 1,450 people, women and men who lost their lives as a result of the most brutal natural catastrophe that our country has ever suffered in its history," said interim President Delcy Rodriguez.

Some 3,150 people were injured and 12,721 displaced while 774 buildings have collapsed, she said.

National Assembly President Jorge Rodriguez said on Sunday that rescue teams remained active trying to find survivors.

So far this weekend, the government said at least 33 people had been rescued by Saturday evening, including several children, while tens of thousands remained unaccounted for.

The US Geological Survey estimated ‌more than 10,000 ⁠deaths were possible from the magnitude 7.2 and 7.5 quakes, which would place them among Latin America's deadliest of the last century.

"There exists a window of roughly three days, 72 hours, where the probability afterwards decreases that you can save people alive," said Sebastian Eugster, the leader of the Swiss rescue team.

An 80-strong team had found multiple people alive in the rubble thanks to alerts from their eight search dogs, but had not been able to pull them out in time to save them, he added.

June 27 evening had already marked 72 hours since the quakes.
