U.S. halts military engagements with Russia in rebuke over Ukraine

WASHINGTON (Reuters) - The United States on Monday suspended all military engagements with Russia, including military exercises and port visits, as Washington sought ways to punish Moscow over its military intervention in Ukraine without escalating the crisis.

The announcement from the Pentagon came hours after President Barack Obama warned the U.S. government will look at a series of economic and diplomatic sanctions that would isolate Moscow. The United States also put trade and investment talks with Russia on hold.
