North Korea fired two short-range ballistic missiles early on Wednesday (local time), the South Korean military said, according to Reuters.
The latest launches were from the Hodo peninsula on North Korea’s east coast, South Korea’s Joint Chiefs of Staff (JCS) said in a statement. It said it was monitoring in case of additional launches.
The JCS in Seoul said later the North had fired ballistic missiles that flew about 250 km (155 miles). The South Korean news agency Yonhap said they appeared to be a different type to previous launches.
Colonel Lee Peters, a spokesman for US military forces in South Korea, said, “We are aware of reports of a missile launch from North Korea and we will continue to monitor the situation.”
Japan’s defense ministry said no missiles had reached Japanese territory or its exclusive economic zone, and the launches did not threaten Japan’s immediate security.
The incident comes a week after North Korea test-fired two new short-range ballistic missiles toward the East Sea, also known as the Sea of Japan.
North Korea later said the test was intended to send a warning to South Korea and was "personally organized" by North Korean leader Kim Jong Un.
The test came as talks between the US and North Korea on denuclearization continue to stall. The talks broke down after the failed summit between Kim and US President Donald Trump in February in Vietnam.
Trump abruptly ended that summit with Kim, explaining that, while "we had a productive time," no deal was signed.
Trump met with Kim again last month, becoming the first US president to step onto North Korean soil at the demilitarized zone. He said the two leaders agreed to start working-level talks on a denuclearization deal.
