The death toll from Haiti's powerful earthquake jumped to over 1,200 on Sunday, as crews desperately dug through collapsed buildings for survivors in the Caribbean nation still reeling from its president's assassination.

In Les Cayes, as in other hard-hit cities on the southwestern peninsula, most of the population spent the night sleeping outdoors in front of their houses - or what remained of them - amid fears of new aftershocks.

The streets there were filled with the grinding of heavy equipment lifting debris from collapsed buildings, as well as the quieter sounds of people pulling away rubble by hand while searching for the missing.

"Thanks to God and also to my phone, I'm alive," said Marcel Francois, who was rescued from his collapsed two-story home in Les Cayes.

His younger brother Job Francois said a desperate-sounding Marcel had called to say, "'Come save me, I'm under the concrete'... He told me he couldn't breathe, that he was dying."

The neighbors and Job spent hours freeing him and his 10-year-old daughter from the heavy debris.

At least 1,297 people were killed in the 7.2-magnitude quake that struck Saturday about 100 miles (160 kilometers) to the west of the densely populated capital Port-au-Prince, which was devastated in a massive 2010 quake.

Some 13,600 buildings were destroyed and more than 13,700 damaged, trapping hundreds under rubble and leaving more than 5,700 people injured, the country's civil protection agency said in an update.

Rescuers faced new pressure with Tropical Depression Grace approaching, raising fears of torrential rainfall, flash floods and mudslides from late Monday, according to the US National Weather Service.

The US and other nations have pledged to help Haiti cope with this latest disaster. 

Deputy Secretary of State Wendy Sherman spoke with Haiti's Prime Minister Ariel Henry on Sunday and said the US was "already putting resources in place" to bolster the country's emergency response, spokesman Ned Price said in a statement.

USAID head Samantha Power tweeted Sunday that her agency had deployed a 65-person urban search and rescue team - equipped with "specialized tools, equipment & medical supplies" - to join an earthquake disaster response team already in Haiti.

Haiti's neighbor the Dominican Republic said it was shipping 10,000 food rations and medical equipment. Mexico also sent an aid shipment. Cuba and Ecuador dispatched medical or search-and-rescue teams.
