LH gear collapse, runway excursion, glideslope antenna hit, fuel leak/fire, self evacuation.
In the first 5 seconds of the video in post #1 we can see the right wing high, and the left wing dragging on the ground. Thus it seems that the LH main gear failed (the reason for that will be the root-cause of this accident).
The aircraft departs the runway to the left, hits the glideslope antenna (radome damage and right wing debris), loses its undercarriage when traversing the grass, and has a small fire fed by the right wing fuel tank damage.
Then the video on post #6. The unsupervised passengers next to the over-wing exits then see the smoke and start an evacuation - the engines are still spooling down when the video starts, and normally the captain would not initiate an evacuation with the engines running. Both sides were opened, but it seems the evacuation was only on the left side. Then, some time later (59s into the video) the crew/captain initiates the evacuation command, and door 1L was opened, a few seconds before the fire trucks arrived.
A good outcome.
