Nations reacted swiftly Tuesday in condemning a North Korean artillery attack that South Korea said killed two marines and wounded 15 soldiers and civilians.
The strongest reaction came from South Korean President Lee Myung-bak, who ordered his military to punish North Korea "through action," not just words, the official Yonhap news agency said.
"The provocation this time can be regarded as an invasion of South Korean territory," Lee said during a visit to the headquarters of the Joint Chiefs of Staff in central Seoul. "In particular, indiscriminate attacks on civilians are a grave matter."
The United States also offered quick comment, with the White House saying it "strongly condemns" the "belligerent action" by North Korea.
