Four Indonesians were found alive on a boat that drifted north to a remote Indian Ocean island after a tsunami devastated their homeland, a military spokesman said Monday.

"The Indonesians have been brought here. They are at the Coast Guard jetty," army commander Salil Mehta told reporters in Port Blair, the capital of the Indian archipelago of Andaman and Nicobar islands (search).

The independent Indian television station Aaj Tak reported that the four men could barely speak and would only say "Indonesia" when asked their names. The station said the men were in a motor boat when the 9-magnitude earthquake struck the Indonesian island of Sumatra (search) on the morning of Dec. 26, setting off powerful tsunamis that are believed to have killed more than 150,000 people.
