Test of apparent ICBM theoretically capable of striking US mainland comes amid warnings over North Korean troops in Ukraine

North Korea has test launched a long-range missile theoretically capable of striking the US mainland in another display of defiance by the regime amid growing warnings over its troops’ participation in the war in Ukraine.

US officials said they believed Thursday’s launch was that of an intercontinental ballistic missile [ICBM] but did not say how they had reached that assessment. Japan’s defence minister, Gen Nakatani, said the missile had flown higher and for longer than others tested by North Korea.
