El Salvador President Nayib Bukele said his country prepared 50 tonnes of equipment and supplies, as well as 300 rescuers who are "ready to depart for Caracas".

The presidents of Ecuador and Mexico both said they would be sending aid, while Brazilian President Luiz Inácio Lula da Silva said his country would assess what assistance it could extend to its "sister nation".

The Dominican Republic would be sending specialised teams for search, rescue, and emergency care from its armed forces, President Luis Abinader said, and Chile's President José Antonio Kast Rist offered support with coordinating humanitarian aid.

The United Nations' relief chief said it was "fully mobilised" to support the people of Venezuela, including the rapid deployment of search and rescue teams and strengthening its humanitarian mission in the country.

"The coming days will require a massive collective effort," Tom Fletcher said in a statement.

The EU activated its satellite surveillance system to help recovery efforts and was ready to "step up assistance", its commissioner for crisis management Hadja Lahbib said.
