Ukraine ambushes Russian convoy in Kursk as Kremlin declares emergency

Video circulated by Russian military bloggers shows destroyed vehicles on the E38 east-west highway

Ukrainian forces staged an overnight ambush on a Russian convoy 25 miles inside the international border in Russia’s Kursk province, as the Kremlin declared a federal emergency and said it was transferring extra forces to try to snuff out a four-day incursion that has badly damaged its credibility.

A video circulated by Russian military bloggers showed a destroyed convoy, with bodies just visible inside some trucks, on the E38 east-west highway at Oktyabrskoe, a location far deeper inside Russia than any previously confirmed fighting since Ukraine’s forces crossed the border on Tuesday.
