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.

Azerbaijan Airlines’ Embraer 190 was en route from Baku to the Russian city of Grozny when it was diverted for reasons yet unclear and crashed while making an attempt to land in Aktau in Kazakhstan.

Experts say evidence in the Azerbaijan Airlines plane crash in Kazakhstan points to a possible midair explosion, not an encounter with a flock of birds.
