A Palestinian has rammed his vehicle into an Israeli police officer in the West Bank, seriously injuring him before he was shot and killed, police said.

It was the latest in a nearly two-month rash of violence that has seen almost daily Palestinian attacks on Israeli civilians and soldiers.

Police spokeswoman Luba Samri says the officer was seriously wounded in the attack.

In a bid to deter attackers, Israel’s parliament this week passed a law toughening penalties against Palestinians for throwing rocks at civilians and security personnel, a daily occurrence that has caused casualties.

The law places a minimum sentence of three years on offenders and strips rock-throwers of their social security benefits, a punishment that applies to Palestinians in east Jerusalem.

The parents of minors convicted of rock-throwing could also have their social security benefits annulled during the period of the offender’s sentence.

Israel’s parliament, the Knesset, announced the adoption of the law on its website on Tuesday. The legislation was first introduced months ago, before the current unrest began.

The violence began with clashes at a sensitive Jerusalem holy site and quickly spread across Israel and into the West Bank and Gaza Strip.

Eleven Israelis have died, mostly in stabbing attacks, while 70 Palestinians have been killed, including 44 Israel said were attackers.
