At least a dozen people died in a plane crash in southeastern Kazakhstan on Friday after a Bek Air-operated jet came down shortly after takeoff and hit a building.

The twin-turbofan Fokker 100 aircraft was carrying 98 people including five crew members, Kazakh Deputy Prime Minister Roman Sklyar said at a news conference in Almaty. Another 49 were injured, with 18 in serious condition.

The plane’s tail touched the ground twice during takeoff before gaining altitude and this may have caused the crash, Sklyar said. Among the passengers were two Ukrainian citizens, one Kyrgyz and one Chinese. The captain died in the crash.

The aircraft took off at 7:05 a.m. en route to the capital, Nur-Sultan and at 7:22 a.m. lost altitude and crashed into a two-story building in the area of Almerek village, according to a post on Almaty airport’s Facebook page. According to Flightradar24, the plane was a 23-year-old Fokker 100.

In another post on Facebook, the airport published two pictures that listed the names of 60 survivors it said had received medical aid. It wasn’t immediately clear why the plane crashed. The weather at the time of the crash was relatively clear amid temperatures just below zero, according to Flightradar24.

Bek Air didn’t immediately respond to calls for comment. President Kassym-Jomart Tokayev issued a statement offering condolences.

Bek Air, founded in 2011, is a full-service domestic carrier, operating from a hub at Uralsk Airport in northwestern Kazakhstan, according to CAPA Centre for Aviation. The company operates a fleet of Fokker 100 planes, its website shows. The average age of aircraft in Bek Air’s fleet is about 26 years, according to plane tracking website planespotters.net.

Fokker NV along with Fokker Aircraft BV, the aircraft production unit, filed for bankruptcy in March 1996 after its main shareholders stopped supporting the unprofitable company. It was also facing competition from Airbus SE and Boeing Co.
