An explosion ripped through a car late Monday in Gaza City (search), police said, wounding a lawyer who was in the vehicle, as well as two bystanders.

Israel Radio reported that the bombing was criminally motivated, but Palestinian police could not confirm that. The lawyer, identified as Majad Jaafarwi (search), was seriously hurt. The bystanders were treated at the scene for minor injuries.

Police closed off the area after ambulances raced to the scene. Palestinians said Jaafarwi, 55, is well known and is not politically involved.

The Israeli military spokesman said the military was not involved in the incident.

During four years of Palestinian-Israeli violence, Israel has carried out dozens of air strikes aimed at militants in Gaza, but since a Feb. 8 declaration of an end to the violence, Israel has not carried out operations in Gaza.
