At least 10 Haitian migrants were killed and rescuers scrambled to save about 100 more who clung to the hull and mast of an overloaded wooden sloop that capsized in the Bahamas, the U.S. Coast Guard said on Tuesday.

The 40-foot (12-metre), sail-powered coastal freighter ran aground and capsized near Staniel Cay in the central Bahamas on Monday night, officials said. It was presumed to have been heading toward the United States.

Bahamian authorities said they had not confirmed any deaths, but the U.S. Coast Guard put the death toll at 10.
