A Palestinian stabbed and wounded an Israeli officer in annexed east Jerusalem on Saturday before being shot dead, police said.
The officer was taken to hospital with "moderate" injuries after the attack in the walled Old City, police spokeswoman Louba Samri said in a statement.
The attacker, brandishing a knife, stabbed the policeman in one of the alleys of the Old City before the wounded officer shot him dead, the statement said.
A wave of unrest that broke out in October 2015 has claimed the lives of 264 Palestinians, 41 Israelis, two Americans, one Jordanian, an Eritrean, a Sudanese and a Briton, according to an AFP count.
Most of the Palestinians killed were carrying out knife, gun or car-ramming attacks, the Israeli authorities say.
Others were shot dead during protests or clashes, while some were killed in Israeli air strikes on the Gaza Strip.
