U.S.-NATO MEETING: U.S. and NATO military officials will meet today to discuss security guarantees for Ukraine as the White House works to arrange a summit between Ukrainian President Volodymyr Zelenskyy and Russian President Vladimir Putin.

Officials told Reuters that the Pentagon is carrying out planning exercises on the support Washington could offer beyond providing weapons.

The incident highlights the continuing volatility near NATO's eastern border as Russia intensifies aerial attacks on Ukraine.

Two German fighter jets were scrambled to the Romanian-Ukrainian border on Tuesday night in response to a Russian drone attack in the frontier region.
