North Korea fires 10 short-range missiles - Yonhap
Yonhap said the missiles flew for 70 km (45 miles) before splashing into the sea.
North Korea is not banned from short-range missile launches under U.N. sanctions and frequently tests its arsenal.
The North has toned down its bellicose rhetoric towards the South, although it has denounced joint U.S.-South Korean military exercises that are currently taking place.
It undertook a series of short-range missile launches earlier this month as the joint exercises, which North Korea views as a threat to its security, started.
In early 2013, North Korea conducted its third nuclear weapons test, having successfully launched a long-range rocket in 2012 that critics say was aimed at proving technology for an intercontinental ballistic missile.
Both of these are banned under U.N. sanctions.
