Ukraine thwarts Russian advances; fight rages for Mariupol

Ukrainian forces fought off continuing Russian efforts to occupy Mariupol and claimed to have retaken a strategic suburb of Kyiv on Tuesday, mounting a defence so dogged that it is stoking fears Russia's Vladimir Putin will escalate the war to new heights.
"Putin's back is against the wall," said U.S. President Joe Biden, who is heading to Europe this week to meet with allies. "And the more his back is against the wall, the greater the severity of the tactics he may employ."
Biden reiterated accusations that Putin is considering resorting to using chemical or biological weapons, though Pentagon spokesman John Kirby said the U.S. has seen no evidence to suggest that such an escalation is imminent.
The warnings came as attacks continued in and around Kyiv and Mariupol, and people escaped the battered and besieged port city.
The hands of one exhausted Mariupol survivor were shaking as she arrived by train in the western city of Lviv.
