Two people were killed Thursday evening after their car exploded while they were driving on Highway 5 near Petah Tikvah.

Police said an initial investigation showed that the powerful explosion was caused by a bomb planted on the vehicle.

They suspect that the incident was an underworld assassination.

The identities of the two victims were not immediately clear. A second car was damaged by flying debris from the explosion, but its occupants were uninjured.

A Magen David Adom medic official who arrived at the scene said that it “was a strong fire. Pieces went flying out of the car… it was a difficult scene similar to terrorist attacks,” Ynet reported.
