At least 38 people were feared dead when a passenger jet crashed in Kazakhstan after it was forced to divert from its intended destination in southern Russia—an area where Moscow’s air defenses have battled Ukrainian drones in recent weeks.

A passenger plane flying from Azerbaijan to Russia with 67 people on board crashed in Kazakhstan Wednesday, authorities said.

Several passenger plane crashes have occurred worldwide this year, including a Wednesday morning Azerbaijan Airlines wreck that has left dozens feared dead.
