Tuesday's incident appears to mark the third time this year that Palestinians inside Jerusalem have been involved in attacks on Israelis.
Just hours before US Democratic presidential candidate Barack Obama was due to arrive in Jerusalem, a Palestinian went on a bulldozer rampage in downtown Jerusalem – just down the road from the legendary King David Hotel, where Senator Obama is to stay.
The attack, which injured 24, marks the second time this month that such an attack took place on a main thoroughfare in primarily Jewish West Jerusalem, and the second time this month in which the attacker, who was shot and killed, was from Arab East Jerusalem, raising tensions in the city.
Yerah Tucker, an emergency service worker who went to the scene, said Israelis were concerned this was becoming a new pattern of attacks. "Now, everyone who sees a bulldozer in Jerusalem has reason to be scared."
Tuesday's attack appears to mark the third time this year that Palestinians inside Jerusalem have been involved in attacks on Israelis. Palestinians as a population make up close to a third of Jerusalem, and most are permanent residents who hold "blue ID cards" issued by the Israeli government, giving them the right to work or travel anywhere in Israel and receive benefits similar to those of Israeli citizens.
On July 2, a Palestinian from the East Jerusalem neighborhood of Sur Baher killed three people and wounded 30 others when he rammed a bulldozer into a bus and cars on a busy Jerusalem street before being shot dead. In March, a Palestinian from another area of East Jerusalem, Jebel Mukaber, gunned down eight seminary students in the town center. Police prohibited the publishing of details on Tuesday's attacker, but earlier in the day, news wires had identified him as a 22-year-old from Umm Tuba, also in the Jerusalem area.
