MARIUPOL, Ukraine (AP) – Russian strikes have hit near airports in western Ukraine as the military offensive widened, and invading troops kept up pressure on the capital Kyiv and the besieged port city of Mariupol. Authorities say the airstrikes on the Lutsk military airfield on Friday left two Ukrainian servicemen dead and six people wounded. The strikes also targeted an airport near Ivano-Frankiivsk, where residents were ordered to shelters. New satellite photos, meanwhile, appeared to show a massive convoy outside the Ukrainian capital had fanned out into towns and forests near Kyiv with artillery pieces raised for firing in another potentially ominous movement. Ukrainian authorities announced plans for several evacuation and humanitarian aid delivery routes to free people struggling to leave Mariupol.
