“I share with the Hungarian people the pain of the victims’ families. Please accept my sincere condolences,” the letter said.

The Saratov Airlines An- 148 jet was en route to Orsk when it vanished from the radars four minutes after take-off. All 65 passengers and six crew members were killed in the crash.
