Kerry warns Russia of expensive new sanctions

WASHINGTON (AP) — Secretary of State John Kerry is accusing Russia of failing to live up to commitments it made to ease the crisis in Ukraine.

In unusually blunt language, Kerry said Thursday that unless Moscow takes immediate steps to de-escalate the situation, Washington will have no choice but to impose additional sanctions. He said It would be a “grave” and “expensive mistake.” His comments come amid an increasingly bitter war of words over who is to blame for the crisis in Ukraine that is becoming steadily more violent.
