Four people were killed and 13 were injured when a vehicle exploded Thursday in the settlement of Ramla, in central “Israel”.

Shamir Medical Center said that the four succumbed to injuries sustained in the car explosion, adding that six injured people are still undergoing treatment in the hospital, with five others lightly to moderately injured.

“Israeli” police say they ruled out a bomb as a possibility of the blast, as bomb squads found no indication at the scene that the explosion was caused by a bomb.

The police are now investigating other possibilities, such as that a grenade or a Molotov cocktail ignited the explosion – according to “The Times of Israel”.
