A bomb has exploded at a crowded bus stop in Jerusalem, killing a woman and wounding more than 20 people.
An Israeli official says the device was hidden in a bag left at the scene, near the main bus station.
The woman died in hospital.
On Wednesday, Israeli warplanes launched fresh air strikes east of Gaza City, after two rockets were fired into southern Israel.
The BBC reports Jerusalem was hit by a series of bombings - mostly targeting buses and restaurants - during a uprising that began in 2000.
However the attacks have stopped in recent years. Jerusalem last experienced a bus bombing in 2004.
