The UN Security Council has unanimously condemned the sinking of a South Korean warship in March. A statement expressed deep concern over the finding by a South Korean-led inquiry that North Korea was behind it. <br/><br/>But the Security Council also took note of Pyongyang's insistence it had nothing to do with the incident. Seoul's investigators concluded a North Korean torpedo had struck the Cheonan in the Yellow Sea, killing 46 sailors. <br/><br/>The Security Council statement, read out by Nigeria's permanent representative at the UN today, said the attack had endangered peace and security in the region and beyond. It also praised South Korea's government for the restraint it had shown since the incident and called for appropriate and peaceful measures to be taken against those responsible.
