North Korea has threatened to sever the ties and reiterated the war threat, as being accused of sinking the ship.
President Lee convened his advisers of National Security Council, to discuss the 'military provocation' came from North which violated the UN charter as well as an armistice agreement. South Korea also demanded a 'stern global response' to the report. US and Japan had informed that they would support measures against the North.
“As the issue is grave and significant, we should be very prudent about every corresponding measure we prepare without single mistake," quoted a statement on the Presidential website, as a reason for the urgent meeting.
The international panel had released a report yesterday, May 20, providing the evidence including torpedo parts as the 'conclusive proof' of North Korea's role in the sinking of the ship with a torpedo in March 2010, which killed 46 sailors.
