Israeli police have clashed with several hundred Palestinians following reports that an Arab teenager was kidnapped and a body found in a Jerusalem forest.
Palestinians hurled stones at forces who responded with tear gas, police spokesman Micky Rosenfeld said. Security has been heightened around the city.
Mr Rosenfeld said police received reports that an Arab teenager was forced into a car. A body was later found but police have not yet established whether the two incidents are related.
The events come days after the bodies of three missing Israeli teenagers were found in the West Bank.
Yesterday, several hundred right-wing Israeli youths marched through Jerusalem, shouting for revenge.
Mr Rosenfeld said the death may have been a revenge killing but the motive could also have been criminal.
