Bus explodes in Jerusalem

JERUSALEM (AP) — An Israeli rescue service says a bus has exploded in the heart of Jerusalem, wounding at least 15 people and raising fears of a return to the Palestinian suicide attacks that ravaged Israeli cities a decade ago.

Police Monday initially called the blast a terrorist attack, but later said all options were being examined.

The Magen David Adom rescue service says 15 people were wounded, including two seriously. Images show fire and large plumes of smoke billowing from the back of the bus.

The blast comes amid a seven-month wave of Palestinian attacks, mostly stabbings, in which 28 Israelis and two Americans have been killed. At least 189 Palestinians have been killed in that period. Israel says most of the dead were attackers, with the rest killed in clashes.
