The North's military appears to be making preparations for a counterattack, removing covers from coastal artillery guns and forward-deploying some artillery batteries, a military source said. In the run-up to last month's attack, the North had forward-deployed four artillery batteries and uncovered 14 coastal artillery guns.
South Korea has deployed a 7,600-ton guided-missile Aegis destroyer, the Sejong the Great, and a 4,500-ton destroyer to the Yellow Sea, while putting F-15K fighter jets on standby at an air base in the southeastern city of Daegu, officials said.
"Our military is maintaining full preparedness to respond to possible North Korean provocations while watching the North's military moves closely," said a military official, pledging to give an "immediate and strong" response in case of provocations.
