North Korea has fired five short-range projectiles into the sea off its east coast, South Korea's military says, amid heightened tension over the isolated country's nuclear and rocket programs.
The unidentified projectiles were launched on Monday from south of the city of Hamhung and flew about 200km, landing in waters east of North Korea, South Korea's Joint Chiefs of Staff said in a statement.
On Friday, North Korea fired two mid-range ballistic missiles into the sea in defiance of tough new UN and US sanctions slapped on the country following nuclear and rocket tests earlier this year.
In recent weeks, North Korea has stepped up its bellicose rhetoric, threatening pre-emptive nuclear strikes against Washington and Seoul and firing short-range missiles and artillery into the sea.
The North protests annual ongoing joint US-South Korea military drills.
