RUSSIA ANNOUNCES ICBM TEST AS UKRAINE CLINGS TO KEY PORT CITY

MUKACHEVO, UKRAINE — Russia and the West traded threats and diplomatic slights Wednesday, as another Russian deadline for Ukrainian forces to surrender the key port city of Mariupol passed without movement, and Moscow’s forces continued pummeling a broad swath of the country’s east.

Russia’s Defense Ministry announced that it had successfully conducted the first test of a new intercontinental ballistic missile that President Vladimir Putin said “is capable of overcoming all missile defense systems” and would make those who “try to threaten our country think twice.”

Putin also claimed, according to Russian news reports, that the nuclear-capable RS-28 Sarmat missile was made using “exclusively” domestically manufactured parts — an apparent shot at Western sanctions, which have kept Moscow from obtaining critical components for other weapons systems it has relied upon in its assault on Ukraine.
