Russian aircraft flies within several feet of US navy plane over Mediterranean Sea

The incident comes at a time of heightened tension between the US and Russia over Ukraine

Russian aircraft came close to three US navy planes in the Mediterranean Sea over the weekend, the Pentagon said on Wednesday, at a time of heightened tensions between the two countries over Russia's military buildup along its border with Ukraine.

While such interactions are not rare between the United States and Russia, it comes at a particularly delicate time and a heightened concern about any accidents or miscalculations.
