A Navy aircraft carrier and guided missile cruiser collided off the East Coast during training operations, sending one of them back to land for repairs, the Navy said. No one was injured.

The ships - the carrier USS Theodore Roosevelt, based in Norfolk, and the cruiser USS Leyte Gulf, based in Mayport, Fla. - were about 100 miles east of Cape Hatteras, N.C., when they collided early Monday, Navy officials said.Most of the damage aboard the Roosevelt was at its stern, while damage to the Leyte Gulf was limited to its bow above the water line, said Lt. Cmdr. Bob Ross, an Atlantic Fleet spokesman.
