JERUSALEM - A Palestinian bulldozer driver went on a deadly rampage on a busy Jerusalem street Wednesday, plowing into a string of vehicles and pedestrians, killing at least two people and wounding more than 20 before he was shot dead by police.

The attack wreaked havoc and left a large swath of damage in the heart of downtown Jerusalem. Traffic was halted, and hundreds of people fled through the streets in panic as medics treated the wounded.

There was no immediate claim of responsibility, but Israeli police referred to the attacker as a “terrorist.”

At the scene of the attack, a half-dozen cars were flattened and a third was overturned by an enormous Caterpillar tractor. A bus also was overturned, and another bus was heavily damaged. Israel’s national rescue service confirmed two deaths, and the two bodies lay motionless on the ground covered in plastic. Local TV was reporting four dead.

A woman sprinkled water over a baby’s bloodied face, a rescue worker stroked the hair of a dazed elderly pedestrian and a loved one raised the bleeding leg of a woman sitting outside the overturned bus.

“I saw the bulldozer smash the car with its shovel. He smashed the guy sitting in the driver’s seat,” said Yaakov Ashkenazi, an 18-year-old seminary student.

Esther Valencia, a 52-year-old pedestrian said she barely escaped the carnage. “He almost hit me. Someone pushed me out of the way at the last moment. It was a miracle that I got out of there.” Sixteen-year-old Eyal Lang Ben-Hur, was in a bus when the driver yelled out, “Get out of the vehicle! Everyone out!” People fled in a panic, he said, and the bus was hit an instant later.

Israel’s national rescue service said at 22 people were wounded, with at least 14 people hospitalized. Local television reported that four people had died, although rescue services put the number at two.

Car picked up ‘like a toy’Injured people sat dazed on the ground amid piles of broken glass and blood stains on the street. A baby had blood all over its face, and the driver of the bulldozer was slumped motionless over the steering wheel.

“Where’s the baby? Where’s the baby?” said one distraught man as he ran from the overturned bus.

Yosef Spielman, who witnessed the attack, said the bulldozer picked up a car “like a toy.”

“I was shocked. I saw a guy going crazy,” he said. “All the people were running. They had no chance.”

At one point, witnesses said police attacked the perpetrator, after which the witnesses said he slumped over with his eyes closed. Then he suddenly lifted himself back up and continued his rampage, the witnesses said.

Hen Shimon, a 19-year-old solider, said the whole scene was a “nightmare.”

“I just got off the bus and I saw the tractor driving and knocking everything down in his path,” she said. “Everything he saw he rammed. He had a gun and started shooting at a police officer.”

In a statement, police said a “terrorist” had carried out the attack but gave no further details.

Sporadic attacks

The attack occurred in an area where Jerusalem is building a new train system. The project has turned many parts of the city into a big construction zone.
