They're believed to have attacked Egyptian merchant ship off Yemen.
DUBAI, United Arab Emirates - A team of specialized American sailors apprehended(逮捕) 17 suspected pirates who attacked an Egyptian merchant ship in the dangerous waters off Yemen, the U.S. Navy said Thursday.
The sailors from the guided-missile(制导导弹) cruiser(巡洋舰) USS Gettysburg also seized eight assault rifles and a rocket-propelled grenade(手榴弹) launcher when they boarded the pirates' vessel Wednesday, said the Navy's Bahrain-based 5th Fleet in a statement.
The Gettysburg launched the operation with the help of the Korean Destroyer ROKS Munmu the Great after the pirates fired at the Egyptian-flagged motor vessel Amira about 75 miles south of Yemen's al-Mukalla port, the Navy said. Both ships dispatched(派遣) helicopters during the mission.
