The BBC also “happened” to have an office right opposite the attack, and here’s a vivid account from that source:

I spoke to a security guard who I know, from the bank next door, who told me he had killed the driver.

He showed me his empty magazine case from his gun, but he clearly hadn’t killed the driver because then, just a few metres in front of us, the bulldozer started off again down the street, slowly zigzagging with – extraordinary to relate – two people, maybe three, inside the cab, having a huge fight.

The cab of the bulldozer itself was shaking violently as the tussle went on.

The bulldozer itself was only moving slowly and it allowed an Israeli policeman clad in black to climb on the bonnet of the bulldozer and he loosed off several shots at point-blank range into the driver’s head, which jerked against the side of the cab, and then the body of the driver was slung onto the road.

And it was at that stage that we were able to back off and have a look at the trail of destruction which was remarkable and unpleasant to look at.

There was a woman driver who had been flattened by the bulldozer, still somehow wedged behind her steering wheel.

I told somebody once that human see with the brain. Our eyes project in inverted image upon the retina, but it is rectified in real time. To a Filipino a car is an recreational vehicle; to a Chinese it’s a delivery van. To a Jihadi it’s a bomb. When you see a bulldozer, remember that it’s not a bulldozer.
