Russia won't say if it mistakenly downed an Azerbaijani plane on Christmas. But it acknowledges the crash came amid a Ukrainian drone attack in its republic of Chechnya.

Russia's head of aviation Dmitry Yadrov claimed a Ukrainian drone attack was underway in Grozny before the plane crashed.

Azerbaijan Airlines Flight 8243 was scheduled to travel from Baku, the capital of Azerbaijan, to Grozny, a city in the Russian region of Chechnya, on Wednesday, but was diverted and ultimately crashed on the other side of the Caspian Sea, less than two miles from the airport in Aktau, Kazakhstan.
