Bomb rocks Jerusalem bus stop, killing woman

The attacks came hours after a bomb struck a crowded bus stop in central Jerusalem, killing one woman and wounding more than 20 other people. No group claimed responsibility for the bombing, but Israeli authorities blamed Palestinian militants.

Israel threatened harsh retaliation for the bombing, the first in Jerusalem in several years.

The bombing came against a backdrop of Palestinian rocket attacks from Gaza and Israeli reprisal raids. The recent wave of violence has threatened to end a lengthy period of relative calm.
