Iranair Tour crash
 

Has anyone heard about the Iranair Tour (TU 154)crash.And maybe the reason.
Iranian news agency announced "A TU-154 belonging to Iranair Tour crashed this afternoon1445 local time just skidded -off the runway after it's landing gear colapsed shortly after touch down and this caused a fire (Explosion????) braking in the Cabin,which it caused 28 Pax to get killed and more to injure.And the rest not harmed and went to the hotel."
They also added that, none of the flight deck member got harmed.
I also saw the footage; the plane had fire alomost from the mid section.and the engines looked also clean.
Can anyone shed a light to what would be the cause of such accident please?
I 'm interested on this for my own personal experience.appreciated & wish happy and safe flying for everyone.

Ok - i just heard an interview with an injured Passenger.He said "shortly after landing the plane started with a lot of vibrations then he noticed one of the main landing gear strut brok a part, which it caused the plane to shift on one side and then started to skidding on the belly and this caused a fire to brake down from the front"
