A U.N. official says the bodies of two teenagers have been found near a capsized Haitian sailboat, raising the death toll to 13.

U.N. mission spokesman David Wimhurst says many passengers apparently swam the 150 yards to shore after the boat began taking on water. It is not known how many people are still missing.

The boat is believed to have been carrying at least 100 people, plus cargo along Haiti’s southern peninsula to the capital when it tipped late Saturday night.

Bodies of 11 people were taken to a Port-au-Prince morgue on Sunday. Wimhurst said the bodies of a boy and a girl were found early Monday.
