US considers sanctions to punish Putin over Ukraine

WASHINGTON — Secretary of State John F. Kerry, denouncing what he called Russia’s invasion of Ukraine as an “incredible act of aggression,” said the United States is considering an array of economic sanctions to persuade Russian President Vladimir Putin to change course or to punish him if he refuses.

The decision by Russian President Vladimir Putin to send troops to Crimea, a region of Ukraine, “is really a stunning willful choice by President Putin to invade another country,” Kerry said on CBS’s “Face the Nation,” one of several Sunday morning TV shows on which he appeared.
