North Korea launches "likely" ballistic missiles, U.S. official says

North Korea on Thursday fired two projectiles that are "most likely" short range ballistic missiles into the Sea of Japan, a U.S. official said. 

A short range ballistic missile launch would be a violation of United Nations resolutions, marking a slight ratcheting up from last weekend's launch of two short range cruise missiles, which are not banned by sanctions, according to a U.S. official.  Over the weekend, North Korea launched two cruise missiles west into the Yellow Sea in the first known weapons test during the Biden administration.
