The military on Thursday called in FBI hostage negotiators to help end a standoff with Somali pirates holding a US ship captain hostage.
The pirates were holding the captain in a drifting lifeboat, with a US warship watching nearby.
FBI spokesman Richard Kolko said FBI hostage negotiators were "fully engaged" in the standoff.
The pirates took Capt. Richard Phillips as a hostage after an attack on a US cargo ship. The American crew retook the ship and the pirates fled into the lifeboat. Hostage negotiators and military officials were working to free Phillips.
