"Torpedo 'likely' sank South Korea ship"

"South Korea's defence minister has renewed speculation a torpedo could have caused the blast that sank a warship off its coast last week.

Kim Tae-young said it was a "likely possibility" the Cheonan had been hit by such a missile, but that all possibilities needed to be considered.

Mr Kim did not say who would have fired a torpedo or under what circumstances it could have happened."
