Israeli rescue services say there has been an explosion on a bus across from the military headquarters in Tel Aviv.
The agency says at least 10 people were hurt in Wednesday's blast. The explosion comes amid an ongoing Israeli operation against Gaza's Hamas rulers aimed at stopping Palestinian rocket fire.
Zaki Heller from the Israeli rescue services says the wounded have varying degrees of injuries. It was unclear if anyone was killed.
An Israeli driver who witnessed the explosion told Army Radio the bus was "completely charred inside."
