North Korea has launched multiple ballistic missiles into the sea on Sunday, with experts warning Pyongyang is firing warning shots amid the Iran conflict and possible talks between the United States and South Korea.

Seoul/Tokyo, April 19 (Jiji Press)--North Korea fired several short-range ballistic missiles toward the Sea of Japan from an area around Sinpo in the east of the country around 6:10 a.m. Sunday, the South Korean military said. The missiles are believed to have traveled about 140 kilometers.

SEOUL (Reuters) - North Korea said on Saturday it has successfully conducted an underwater test-fire of a submarine-launched ballistic missile, which, if true, would indicate progress in the secretive state's pursuit of building missile-equipped submarines.
