HAVANA -- With ports mended and weather cleared, Caribbean officials struggled to get aid to islands devastated by Hurricane Irma on Monday and tried to take full stock of the damage caused by the Category 5 storm.

At least 34 people were reportedly killed across the region, including 10 in Cuba, whose northern coast was raked by the storm. Cuban state news media said most of those died in Havana, where Irma pushed seawater deep into residential neighborhoods.

To the east, in the Leeward Islands known as the playground for the rich and famous, many criticized governments for failing to respond quickly to the hurricane, which flattered many towns and stripped the lush green hills to a brown stubble.

Residents have reported shortages of food, water and medicine, and many have complained of 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 has sent a navy ship and almost 500 troops to help people on the British Virgin Islands, Anguilla and the Turks and Caicos islands that were pummeled by the hurricane.

The U.S. government said it was sending a flight Monday to evacuate its citizens from one of the hardest hit islands, St. Martin. Evacuees were warned to expect long lines and no running water at the airport.

New York City resident Tiffany Bender, who was staying at an Airbnb on the Caribbean island of St. Martin during Irma, told CBSN she and her friends are trapped without a way to get off the island.

"We are just asking that not just for ourselves -- please, please call your local electives, call your assemblymen, call your senators, call your embassies and tell them you have citizens who are stranded here, Anguilla, St. Bart's and we just need to go home," Bender said.

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 filled with aid. A French military ship was scheduled to arrive Tuesday with materials to build temporary housing.

Some 70 percent of the beds at the main hospital in the French portion of St. Martin were severely damaged, and more than 100 people in need of urgent medical care have been evacuated. Eight of the territory's 11 pharmacies were destroyed, and Guadeloupe was sending medication.

On Tuesday, French President Emmanuel Macron was scheduled to arrive in St. Martin to bring aid and fend off criticism that he didn't do enough to respond to the storm's wrath.

Interior Minister Gerard Collomb said the "whole government is mobilized" to help and the pillaging that hit the island in the immediate aftermath of the storm had stopped.

Macron promised to go to the region as soon as weather conditions allowed. Soon after Irma left 10 dead on St. Martin, Category 4 Hurricane Jose threatened the area, halting evacuations for hours before heading out to sea and causing little additional damage.

Also hit hard was Cuba, where central Havana neighborhoods along the coast between the Almendares River and the harbor suffered the brunt of the flooding. Seawater penetrated as much as one-third of a mile inland in places.

Cuban state news media on Monday reported 10 deaths despite the country's famed prowess at disaster preparations. More than 1 million people were evacuated from flood-prone areas.

Hector Pulpito recounted a harrowing night at his job as night custodian of a parking lot that flooded five blocks from the sea in Havana's Vedado neighborhood.

"This was the worst of the storms I have been through, and the sea rose much higher," Pulpito said. "The trees were shaking. Metal roofs went flying."

Cuban state television reported severe damage to hotels on the northern keys off Ciego de Avila and Camaguey provinces.

The Communist Party newspaper Granma reported that the Jardines del Rey airport serving the northern keys was destroyed and posted photos to Twitter showing the shattered terminal hall littered with debris.
