An Azerbaijan Airlines commercial jet carrying 62 passengers and five crew members crashed in the Kazakhstani city of Aktau. The Embraer ERJ-190 attempted an emergency landing following initial reports of a "bird strike." Early reports indicate there are 28 survivors.

"Flight #J28243 that crashed near Aktau Airport in Kazakhstan is an Azerbaijan Airlines Embraer ERJ-190 with registration 4K-AZ65," flight tracking website Flightradar24 wrote on X. 

Flightradar24 said, "J28243 took off from Baku at 03:55 UTC time and was flying to Grozny. The aircraft was exposed to strong GPS jamming which made the aircraft transmit bad ADS-B data. At 04:40 UTC we lost the ADS-B signal. At 06:07 UTC we picked up the ADS-B signal again before it crashed at 06:28 UTC."
