A survivor of a plane crash in Kazakhstan described the scene on board as "like in a movie" with cries and screams.

"I heard a terrifying sound before the plane started losing altitude and tilting," recalls a female passenger on flight Z9 2100 carrying 98 people from Bek Air.

The Fokker-100 disappeared from radar this morning shortly after takeoff from Almaty, Kazakhstan's largest city, on its journey to the capital Nur-Sultan. The Kazakh Civil Aviation Commission said the plane "lost altitude during takeoff and crashed into concrete barriers" before hitting a two-story building.

At least 15 people, including 6 children, were killed and 66 were taken to hospitals, some in serious condition. The location of the accident in Almerek village, just at the end of the runway, has been sealed off.

Businessman Aslan Nazaraliyev, another surviving passenger, said the plane started shaking about two minutes after taking off and taking altitude. "At one point we started to fall, but not vertically but at an angle. It seems the plane has lost control," the witness said.

The government has not made any hypotheses about the cause of the accident, and Bek Air has not commented on the accident. According to the Reuters reporter, the scene of the accident appeared dense fog.

"Those responsible for the accident will face severe punishment according to the law," Kazakh President Kassym-Jomart Tokayev wrote on Twitter, and offered condolences to the victims and their families. He also pledged to compensate families and set up a government committee to investigate the accident.

This is not the first serious plane crash in Almaty. In January 2013, a passenger plane from the northern town of Kokshetau crashed near the city, killing 20 people. A month earlier, 27 people were killed when a military plane carrying senior security officials crashed near the city of Shymkent, south of Kazakhstan.
