HAVANA — With ports mended and weather cleared, officials struggled Monday to get aid to Caribbean islands devastated by Hurricane Irma and tried to take stock of the damage caused by the Category 5 storm.
At least 34 people were reported to have been killed in the region, including 10 in Cuba, whose northern coast was raked by the storm. Cuban state media said most of those died in Havana, where seawater surged deep into residential neighborhoods.
To the east, in the Leeward Islands known as the playground for the rich and famous, governments came under criticism for failing to respond quickly to the hurricane, which flattened many towns and turned lush, green hills to a brown stubble.
Residents have reported food, water, and medicine shortages, as well as looting.
British Foreign Secretary Boris Johnson defended his government’s response to what he called an ‘‘unprecedented catastrophe’’ and promised to increase funding for the relief effort. Britain sent a navy ship and almost 500 troops to the British Virgin Islands, Anguilla, and the Turks and Caicos islands.
The US government said it was sending a flight Monday to evacuate its citizens from St. Martin, one of the hardest-hit islands. Evacuees were warned to expect long lines and no running water at the airport.
A Royal Caribbean Cruise Line ship was expected to dock near St. Martin to help in the aftermath, and a boat was bringing a 5-ton crane capable of unloading large shipping containers of aid. A French military ship was scheduled to arrive Tuesday with materials for temporary housing.
The island is divided between Dutch and French territories. About 70 percent of the beds at the main hospital in the French portion were severely damaged, and more than 100 people needing urgent medical care were evacuated. Eight of the territory’s 11 pharmacies were destroyed, and Guadeloupe was sending medication.
Dutch King Willem-Alexander flew to St. Maarten to see the devastation and express gratitude to relief workers. Dutch news outlets showed the king touring the badly damaged Princess Juliana International Airport, which was named for his grandmother.
French President Emmanuel Macron was scheduled to arrive Tuesday in St. Martin to bring aid and fend off criticism that he didn’t do enough to respond to the storm.
The ‘‘whole government is mobilized’’ to help, said Interior Minister Gerard Collomb.
Soon after Irma killed 10 people on St. Martin, Category 4 Hurricane Jose threatened the area, halting evacuations for hours before heading out to sea and causing little additional damage.
In the US Virgin Islands, residents of the capital, Charlotte Amalie on St. Thomas, reported long lines for dwindling supplies of basics such as water, food, and gasoline.
‘‘You get nothing from the city. Nothing. No food. No water. Everything is closed,’’ said Rene Concepcion, who waited for three hours to get water.
Complicating the situation is a noon-to-6 p.m. curfew that usually gives people just enough time to get only one essential item. ‘‘That period of time is the time that we have to do whatever we need: water, food, gasoline,’’ said Gladys Collins. ‘‘Everywhere that you go is a long line.’’
Also hit hard was Cuba, where central Havana neighborhoods along the coast between the Almendares River and the harbor suffered the worst flooding. Seawater penetrated as much as one-third of a mile inland. Cuban state media reported 10 deaths despite the country’s usually rigorous disaster preparations. More than 1 million were evacuated from flood-prone areas.
