(WALL STREET JOURNAL) — The Pentagon announced Tuesday that U.S. troops would be sent for exercises in Eastern Europe to reassure allies on Russia's border, after Ukraine accused pro-Russian separatists of torturing and killing two people and shooting at one of its military planes.
The flareup in tension over Ukraine's eastern region came as U.S. Vice President Joe Biden warned Russia to pull back its troops and abide by last week's multilateral deal reached in Geneva or face the prospect of new sanctions.

Mr. Biden, who met in Kiev with Prime Minister Arseniy Yatsenyuk and other Ukrainian officials, said the U.S. won't allow that deal, intended to immediately begin easing tensions, to instead become "an open-ended process."
