The report states that the Bek Air jet which crashed into a building in Kazakhstan, was carrying 100 passengers and crew when it smashed through a metal fence and into a two storey structure on Friday morning near Almaty.
About 60 people have been taken to hospital, some in a “grave condition”, authorities said.
Authorities had earlier said that 15 people had died but this figure was later revised to 12, with the Almaty healthcare department blaming “confusion on the ground” for the mix up.
The deputy Kazakh Prime Minister has said that the cause of the crash might be pilot error or technical issues.
The Fokker 100 aircraft “lost altitude during take-off and broke through a concrete fence”, according to Kazakhstan’s Civil Aviation Committee.
“Before crashing, the aircraft touched the runway with its tail twice, the gear was retracted,” Deputy Prime Minister Roman Sklyar told reporters.
“A commission… will establish whether this was pilot error or technical issues. The runway was in an idea condition.”
It had been heading for the country’s capital Nur-Sultan, previously known as Astana.
A survivor told news website Tengrinews she heard a “terrifying sound” before the plane started losing altitude.
“The plane was flying with a tilt. Everything was like in a movie: screaming, shouting, people crying,” she said.
A Reuters reporter travelling to the airport soon after the crash said there was thick fog in the area.
Authorities have not suggested any possible cause of the accident and the aviation committee said it was suspending all flights of Fokker 100 aircraft pending an investigation.
Another survivor, businessman Aslan Nazaraliyev, told the Vremya newspaper the plane started shaking while gaining altitude about two minutes after take-off.
“At some point we started falling, not vertically, but at an angle. It seemed like control over the plane was lost,” he said.
The crash site in Almerek village – just beyond the end of the runway – has been cordoned off.
A Reuters reporter saw the plane torn into two parts next to a house half-demolished by the impact. Other planes could be seen taking off from the airport.
“Those responsible will face tough punishment in accordance with the law,” Kazakh President Kassym-Jomart Tokayev tweeted, expressing condolences to the victims and their families
