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.

Mobile phone footage circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball. Some of the videos posted on social media showed survivors dragging fellow passengers away from the wreckage.

Officials say an Azerbaijani airliner has crashed in the Kazakhstani city of Aktau with Kazakhstan’s Emergency Ministry now saying that at least 28 people survived the crash, which could mean that over 30 people are likely dead.
