North Korea fired two short-range missiles at the weekend, South Korean and U.S. officials said, but Washington downplayed the first such tests under U.S. President Joe Biden and said it was still open to dialogue with Pyongyang.

Two senior officials of the Biden administration told a briefing call on Tuesday that the North Korean activity involved weapons systems at the low end of the spectrum that were not covered by U.N. Security Council testing bans.

South Korea’s Joint Chiefs of Staff (JCS) announced that two cruise missiles were fired off North Korea’s western coastal town of Onchon on Sunday morning.

Seoul had detected signs a test was imminent and was monitoring it in real time, a JCS official told reporters on Wednesday. The JCS reports North Korea’s testing of advanced weapons such as nuclear bombs and ballistic missiles nearly in real time but not some tests of lower grade, shorter range weapons.

The launch marks North Korea’s first publicly known weapons test since the U.S President took office in January.

But Biden played down the latest activity, saying “nothing much has changed,” while one senior official said it was “normal” testing and cautioned against “hyping” it.

“No, according to the Defense Department it’s business as usual. There’s no new wrinkle in what they did,” Biden told reporters upon his return from a visit to Ohio, when asked if the test was a provocation.

The Pentagon declined comment on the test, which was first reported by the Washington Post. North Korea’s mission to the U.N. did not immediately respond to a request for comment.
