Seoul - North Korea fired short-range projectiles into the sea off its eastern coast on Thursday, South Korea's defence ministry said, hours after the UN Security Council imposed tough new sanctions on Pyongyang.
After initially describing the launches as being of "short-range missiles," spokesman Moon Sang-Gyun said the ministry was still analysing their exact nature.
The projectiles were fired into the Sea of Japan at 10:00am (0100 GMT), Moon said.
"The South Korean military is monitoring any additional movements from the North," he added.
