JERUSALEM (AP) — An attacker rammed the front end of a massive construction excavator into an Israeli bus on Monday, overturning the vehicle before he was shot and killed by a police officer, authorities said. Police said one person was seriously injured.

Police called the incident a "terrorist attack," indicating that they suspected Palestinian involvement.

Israel's Channel 10 TV showed cellphone video of what it said was the attack. The video showed the yellow construction vehicle slamming the large shovel on its front end into the bus. Israeli media said there were several injuries, including passengers and pedestrians.

Police spokesman Micky Rosenfeld said a police officer in the area opened fire and killed the attacker.

In the past, Palestinian attackers have gone on deadly rampages with bulldozers in Jerusalem traffic.

Tensions have been high between Arabs and Jews in the region amid a monthlong war between Israel and Palestinian militants in the Gaza Strip.
