US to conduct naval exercises with S Korea after attack
South Korea's president has vowed to punish those who carried out the attack
The US has confirmed it will hold naval exercises with South Korea, after a report blamed the North for the sinking of a Southern warship, officials say.
The Pentagon said the joint anti-submarine and other military exercises would start "in the near future".
South Korean President Lee Myung-bak earlier froze trade with Pyongyang, vowing to punish those who carried out the attack.
North Korea has said it will retaliate for any action taken against it.
The country's main newspaper called the investigation an "intolerable, grave provocation".'Unequivocal support'
South Korea has said it will refer the North to the UN Security Council in response to the sinking of the Cheonan - and the resulting death of 46 sailors - in March.
In a move endorsed by the US, President Lee said in a televised address that Seoul would no longer tolerate "any provocative act by the North and will maintain a principle of proactive deterrence".
