North and South Korea exchange fire with hundreds of artillery shells over disputed border
Pyongyang warns of a 'new form' of nuclear test as tensions on peninsula rise

North and South Korea traded hundreds of rounds of live artillery fire across their disputed Yellow Sea boundary today.
It forced South Korean islanders to take shelter the day after the North raised tensions by threatening a new nuclear test.
The South said it had fired more than 300 shells in response to the North firing more than 500 shells during its three-hour military exercise.
About 100 shells fired by the North had landed in South Korean waters next to the disputed border, said Kim Min-seok, the South's Defence Ministry spokesman.
However, none of the shells had hit any land or military installation and there was no indication that either side had fired at any particular target.
When the shelling started, the South scrambled its F-15 fighters to patrol its side of the border. Residents of five nearby South Korean islands were evacuated into shelters.
