Russian military forces have launched a major invasion of Ukraine, escalating the civil conflict in eastern Ukraine into a broader Ukraine War. President Putin has made a televised announcement of a “special military operation” in Ukraine, effectively declaring war.

Russian forces have bombarded strategic sites in Ukraine, including airstrikes and/or missile strikes at Ukrainian airports and air bases. BBC News reports that “Missile strikes and explosions have been reported in several parts of Ukraine, including Kyiv and Kharkiv.”

These airstrikes seem to be supported by artillery bombardments in eastern Ukraine.

Meanwhile, Russian armed forces have crossed the Ukrainian border at multiple points. BBC News confirms that Russian military units have invaded Ukraine from their positions in Russia, Crimea, and Belarus.

BBC News reports on the outbreak of the Ukraine War. The New York Times is providing live updates, as are The Washington Post and France24.
