North Korea fired at least 10 apparent short-range ballistic missiles toward the waters off its eastern coast on Thursday, Seoul said, days after its attempt to put another spy satellite launch into orbit ended in a ball of fire.

South Korean officials said the short-range weapons had been fired from the Sunan area of Pyongyang, traveling around 350 kilometers (215 miles) before splashing down into the Sea of Japan.

In a statement, the military condemned the launches — which put the South Korean capital and a number of important military bases within range — and vowed to "respond overwhelmingly to any provocation."
