Somalia ? As a heavily armed U.S. destroyer patrolled nearby and planes flew overhead Sunday, a Somali pirate spokesman told The Associated Press his group was demanding a $20 million ransom to release a cargo ship loaded with Russian tanks.

The spokesman also warned that the pirates would fight to the death if any country tried military action to regain the ship, and a man who said he was the ship’s captain reported that one crew member had died.

Pirates seized the Ukrainian-operated ship Faina off the coast of Somalia on Thursday as it headed to Kenya carrying 33 Russian-built T-72 tanks and a substantial amount of ammunition and spare parts. The ordnance was ordered by the Kenyan government.
