(AL-JAZEERA) International rescue teams have joined an urgent search for survivors in Venezuela, where people remain trapped under collapsed buildings after two devastating earthquakes on Wednesday.

Countries from across the Americas – including Brazil, Canada, Mexico, Colombia, El Salvador, Cuba and the United States – as well as the United Nations, continued on Friday to send search and rescue teams and humanitarian aid in the aftermath of the quakes. Authorities have raised their estimate of the death toll to 589 people.

“To the Venezuelan people, to those whose loved ones are under the rubble, know that we are determined that help gets to you,” said the UN’s aid chief, Tom Fletcher.
