英法保证向加勒比海飓风灾区提供更多帮助

Emergency workers and National Guard troops are working to find those left stranded in the Florida Keys by Hurricane Irma, while France and Britain pledge to boost their response to those hit by the storms in their territories in the Caribbean.

French President Emmanuel Macron is visiting Saint Martin and Saint Barthelemy on Wednesday, a day after arriving in Guadeloupe where he acknowledged the angry response some people have to what they see as inadequate help from France. Macron promised more supplies and security forces for the islands.

British Foreign Secretary Boris Johnson is touring Wednesday in Anguilla and the British Virgin Islands, two places that took hard hits from Irma last week when it was a powerful Category 5 storm. He also said more security forces and "huge quantities of supplies" were coming, and that he expects Prime Minister Theresa May to announce further aid on Wednesday.

The United Nations is airlifting food and other vital relief to the islands of Antigua, St. Martin, and the Turks and Caicos.

The hurricane killed at least 37 people in the Caribbean and devastated the islands, including Barbuda, which has evacuated all of its citizens to Antigua.

A further 12 deaths have been linked to Irma in the U.S. state of Florida, and a total of six others in Georgia and South Carolina.

The Florida Keys were the hardest-hit area on the U.S. mainland. In addition to rescue operations there, National Guard troops are also working to clear roads and runways in order to allow deliveries of life-saving supplies to the island chain.

The head of the Federal Emergency Management Agency, Brock Long, said that according to preliminary estimates, 25 percent of homes were destroyed and 65 percent sustained major damage.

"Basically, every house in the Keys was impacted in some way or another," Long said.
