UN warship hearing angers N Korea

North Korea says its military will respond if the UN Security Council rebukes it over an alleged torpedo attack on a Southern warship in March.
In a rare news conference, the North's UN envoy Sin Son-ho demanded that Pyongyang be allowed to send a team to investigate the sinking of the Cheonan.
His comments came a day after North and South gave their versions of events to the UN in separate hearings.
The US said the comments represented more "provocative behaviour".
