Haiti's hospitals were swamped this morning by thousands of injured residents after a devastating earthquake, which has killed at least 1,297 people, reports Reuters.
Authorities are now racing to bring doctors to the worst-hit areas before a major storm hits.
The 7.2 magnitude quake on Saturday destroyed thousands of homes and buildings in a Caribbean nation which is still clawing its way back from another major earthquake 11 years ago and is reeling from the assassination of its president last month.
Southwestern Haiti bore the brunt of the blow, especially in the region around the town of Les Cayes. Haiti's Civil Protection Agency said the toll from the disaster had climbed to 1,297 and the hospitals that were still functioning were struggling to cope, as some 5,700 people were injured.
In the northwestern city of Jeremie, another badly hit area, doctors treated injured patients on hospital stretchers underneath trees and on mattresses by the side of the road, as healthcare centers have run out of space.
"We do have a serious issue," said Jerry Chandler, the head of Haiti's Civil Protection Agency.
"There are very important facilities that are dysfunctional as we speak and those that are functional are receiving an overflow of patients," he said.
Covid's impact
The challenge facing Haiti has been exacerbated by the coronavirus pandemic, a severe economic downturn aggravated by fierce gang violence, and a political crisis that has engulfed the troubled nation after the assassination of President Jovenel Moise on 7 July.
Churches, hotels, hospitals and schools were badly damaged or destroyed, while the walls of a prison were opened by the violent shudders that convulsed Haiti. Some 13,694 houses were destroyed, the civil protection agency said, suggesting the toll could rise further.
In Les Cayes, a seafront town of some 90,000 people, rescuers in red hats and blue overalls pulled bodies from the tangled wreckage of one building, as a yellow mechanical excavator nearby helped to shift the rubble.
Haiti's Prime Minister Ariel Henry, who flew to visit Les Cayes, praised the dignity shown by people there even in the midst of their suffering.
"They are affected but resilient. They fight to survive," he said, thanking international agencies and foreign governments for their support.
International aid
Nearby countries, including the Dominican Republic and Mexico, rushed to send desperately needed food and medicines by air and across Haiti's land border. Colombia sent search and rescue personnel.
The United States dispatched vital supplies and deployed a 65-person urban search-and-rescue team with specialized equipment, said Samantha Power, the administrator of the United States Agency for International Development (USAID).
From the Vatican, Pope Francis urged the international community to show support swiftly.
"May solidarity from everyone lighten the consequences of the tragedy," he told pilgrims and tourists at his Sunday blessing in St. Peter's Square.
However, Haiti's government appealed to aid organizations against setting up makeshift camps and urged them to work through the planning ministry, an apparent attempt to avoid the mistakes made following the devastating 2010 earthquake that killed tens of thousands of people.
Many Haitians prepared on Sunday to spend a second night sleeping in the open, traumatized by memories of that magnitude 7 quake 11 years ago that struck far closer to the sprawling capital, Port-au-Prince.
At Port-au-Prince airport, international aid workers, doctors and rescue workers boarded flights to Les Cayes. A U.S. Coast Guard helicopter ferried the wounded.
The rescue and aid efforts will be complicated by Tropical Depression Grace, which is expected to lash Haiti with heavy rainfall on Monday. Some 75 to 100 milliliters of rainfall was expected, which may trigger landslides and cause some rivers to flood, Haiti's Civil Protection Agency said.
"We ask the population to remain vigilant," the agency added.
Thousands of people sleeping in the streets would be exposed to the torrential rains amid a rising risk of water-borne diseases, said Mr Chandler, the head of the agency.
The death toll is expected to rise as telephone network has been down in more remote areas. In difficult-to-reach villages many houses were fragile and built on slopes vulnerable to landslides, said Alix Percinthe, from the ActionAid charity.
He said one local leader had informed him there were 47 deaths in his area not yet reported to regional authorities.
Humanitarian Corridor
Footage of Saturday's aftermath posted on social media showed residents reaching into narrow openings in piles of fallen masonry to pull shocked and distraught people from the debris of walls and roofs that had crumbled around them.
Access to the worst-hit areas was complicated by a deterioration in law and order that has left key access roads in parts of Haiti in the hands of gangs. In a video posted on social media, one gang leader said the armed groups had declared a truce along the route to Les Cayes.
Mr Chandler said boats and helicopters were being used to bring in aid, but the government was working to establish safe access by road. A first convoy of aid had made it through by land to the region of Les Cayes.
The United Nations called for a "humanitarian corridor" to be established so that aid can pass through gang-held territories.
Following President Moise's assassination, which authorities have alleged was carried out by a group of largely Colombian mercenaries and Haitian accomplices, Prime Minister Henry said officials would aim to hold elections for a new president as soon as possible.
However, reports this week suggested that the vote initially earmarked for September would not take place until November.
