Palestinians have accused Israeli extremists of abducting and killing an Arab teenager and burning his body, sparking hours of clashes in east Jerusalem and drawing charges that the youth was murdered to avenge the killings of three kidnapped Israelis.

A Palestinian teen was abducted and killed, Palestinians said, accusing Israeli settlers of carrying out a revenge attack for the deaths of three Israeli youths.

Israeli security forces have arrested two members of the radical Palestinian group Islamic Jihad who intended to blow themselves up in suicide attacks in Jerusalem, radio and newspaper reports said today.
