North Korea has stopped artillery fire into the sea near its disputed border with South Korea but may carry out further provocative acts. Seoul's military said North Korea carried out live fire exercises from Wednesday throughout Friday, firing hundreds of shells into the ocean just north of the sea border. <br/><br/>A defence ministry spokesman said today, there has been no artillery fire by the North near the sea border. The ministry said it was considering shipping more artillery and advanced radar to Yeonpyeong Island and another border island in response to the shelling into the Yellow Sea. North Korea had declared two no-sail zones that straddle the disputed maritime border, effective until March 29, raising tensions on the Korean peninsula. The North says it is conducting a routine artillery drill but Seoul and Washington have criticised the salvos as provocative.
