The missiles fell in the sea east of the Korean peninsula, off the Japanese coast. The launch comes as another US nuclear-powered submarine arrives in South Korea.
Edneüs informs via foreign media that North Korea has fired two ballistic missiles eastward, in apparent reaction to the arrival of a US nuclear-powered submarine at a South Korean naval base.
South Korean and Japanese media reported the launch on Monday, saying the missiles flew about 400 kilometers (248 miles) before falling into the East Sea, also known as the Sea of Japan between the Korean peninsula and Japan.
The missiles were fired from an area near Pyongyang, South Korea's Joint Chiefs of Staff was quoted by the media as saying.
The US military said in a Monday statement that the launches posed no immediate threat to US personnel and territory or to US allies.
