The death toll in Venezuela has climbed to 1,719, Venezuelan lawmaker Jorge Rodriguez said.

Another 5,034 people were injured, he said.

As the death toll rises, United Nations Resident Coordinator in Venezuela Gianluca Rampolla del Tindaro said, "We are procuring … 10,000 body bags."

"At least 2,500 structures are affected, most of which fully collapsed," he said.

Rampolla del Tindaro said the Venezuelan government is still leading search and rescue operations.

"We are beyond the 72-hour critical window, but this is one of the miracles of this country -- rescuers are still being able to pull out alive people," he said. "Yesterday alone, seven persons were moved out of the rubble."

Three Americans have died from the earthquakes and 12 Americans remain missing, the U.S. government has confirmed, according to a senior U.S. official.

More than 300 search and rescue personnel from the U.S. are now working on the ground in Venezuela, a senior administration official said.

The U.S. had committed more than $300 million to the earthquake response, including $200 million in funding for partner organizations and the United Nations Office for the Coordination of Humanitarian Affairs, according to the State Department.

Venezuela's acting president Delcy Rodriguez posted a video on social media showing a man rescued from a collapsed building after 106 hours trapped under the rubble.
