Mariupol's dead put at 5,000 as Ukraine braces in the east

ANDRIIVKA, Ukraine (AP) — The mayor of the besieged port city of Mariupol put the number of civilians killed there at more than 5,000 Wednesday, as Ukraine collected evidence of Russian atrocities on the ruined outskirts of Kyiv and braced for what could become a climactic battle for control of the country's industrial east.

Ukrainian authorities continued gathering up the dead in shattered towns outside the capital amid telltale signs Moscow's troops killed civilians indiscriminately before retreating over the past several days.

In other developments, the U.S. and its Western allies moved to impose new sanctions against the Kremlin over what they branded war crimes.
