Israeli police say its officers have shot dead a knife-wielding Palestinian teen who tried to stab them in east Jerusalem.

Police spokeswoman Luba Samri says the 17-year-old east Jerusalem resident approached a roadblock early Saturday with a butcher's knife and tried to attack officers there. Samri says officers shot the teen dead after he refused to lay down his weapon.

The attack comes a week after Israeli authorities say a 37-year-old Palestinian man intentionally rammed his car into a group of Israeli Jews near Jerusalem, killing one man and seriously injuring a woman.

Israel has seen a number of isolated vehicular and stabbing attacks in Jerusalem in recent months, raising fears of a renewed wave of Palestinian violence like the one that gripped the country a decade ago.
