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.

HUNDREDS of Palestinians clashed with Israeli security forces across east Jerusalem yesterday in the worst rioting in years as a senior Hamas leader called for a new “intifada,” or uprising.

A suicide bomber blew himself up on a Jerusalem bus early today, and Israel Radio said seven passengers and the bomber were killed. At least 20 others were wounded, four seriously, and another bomber blew himself up on the outskirts of the city.
