CBNNews.com - JERUSALEM, Israel - For the second time in less than a month, an Israeli Arab drove a bulldozer on a terror rampage down crowded Jerusalem streets.

Reports of the wounded vary from Israeli news sources, but are estimated to be between 16 and 23 people. Among those injured were a mother and her baby. One man's leg was partially severed when the terrorist overturned his car.

At around 2 p.m. Tuesday, not far from the luxury hotel where Democratic presidential hopeful Barack Obama plans to stay,  eyewitnesses saw a bulldozer barreling down the street, overturning cars.

"[The driver] tried to lower the bulldozer's bucket on the head of a pedestrian, missing her by an inch," one eyewitness reported.

"At first I thought it was an accident, but then he kept going in a zig zag down King David, overturned a car and hit a few [other] cars. The whole thing happened very quickly," he said.

"One car flipped over and others were crushed. I started running in the direction of the bulldozer. People regained their composure within seconds. A guy from Susia, near Mt. Hebron [in southern Judea], shot him in the head and a few minutes later a Border Police officer shot him as well," he said.

The driver also rammed a city bus from the rear and then tried to kill the driver.

"I was driving on the main road when the [bulldozer] hit me in the rear, on the right-hand side," the driver told Israel's Channel 10.

"After I passed him, he turned around, made a U-turn and rammed the windows with the shovel," he said.

"The third time he aimed for my head. He came up to my window and I swerved right. Otherwise I would have gone to meet my Maker," the driver said.

Another eyewitness said the Arab attacker was wearing the large white skullcap of a religious Muslim.

Early reports indicate the driver was an Israeli Arab from a east Jerusalem Arab neighborhood near Sur Bahir.

On July 2, Hussam Taysir Dwayyat, an Israeli Arab from the same neighborhood, killed three Israelis and injured dozens in a similar attack in Jerusalem's city center.
