SEOUL, Jan. 14 (Yonhap) -- North Korea fired two suspected ballistic missiles eastward Friday, South Korea's military said, after Pyongyang publicly warned earlier in the day of a "stronger and certain" response to the United States' imposition of new sanctions.
The Joint Chiefs of Staff (JCS) said the short-range projectiles were launched from a site in North Pyongan Province, a northwestern region bordering China, and that they flew around 430 kilometers at an altitude of 36 km.
It detected one of the missiles at 2:41 p.m and the other at 2:52 p.m.
The intelligence authorities of South Korea and the United States are conducting a detailed analysis for more information, the JCS said.
The North's latest saber-rattling marks its third show of force this year.
South Korea's military is monitoring related North Korean movements and maintaining a firm readiness posture, the JCS said.
Earlier in the day, Pyongyang issued the warning after Washington slapped the sanctions on six North Koreans involved in the regime's weapons of mass destruction and ballistic missile programs Wednesday.
"If the U.S. adopts such a confrontational stance, the DPRK will be forced to take stronger and certain reaction to it," a spokesperson of the foreign ministry said in a statement carried by the North's official Korean Central News Agency. DPRK stands for the North's official name, the Democratic People's Republic of Korea.
The North fired what it claims to be hypersonic missiles on Jan. 5 and Tuesday, in an apparent quest for new advanced weapons amid a deadlock in nuclear talks with the United States.
