Korean truce 'broken'
Updated on 27 May 2009
North Korea threatens to attack South Korea after it agreed to join a US-led initiative to check vessels suspected of carrying equipment for weapons.
North Korea has said it is no longer bound by a truce agreed between the two countries in 1953.
Following this week's nuclear test by North Korea, the South Korean government announced that it would join the US-led Proliferation Security Initiative, which checks vessels suspected of carrying equipment for weapons of mass destruction.
A North Korean army spokesman said that was tantamount to breaking the terms of the truce.
