Cooking gas may have been the first thing to explode in the blasts that took place in a Ra'anana factory Sunday. One account says the factory produces paint, and another says it is a garage.

Five people were slightly hurt, according to Magen David Adom emergency services. They include a man, 25, who was struck in the head by flying debris, and two women who inhaled smoke. The man was taken to Beilinson Hospital in Petach Tikva and the two women were evacuated to Meir Hospital in Kfar Sava.

Terrorism is not suspected.

Eyewitnesses described three or four loud blasts after which a fire broke out near Renanim Mall and smoke began gathering in the sky above Ra'anana.

Thick black smoke has complicated rescue efforts and the attempts by firefighters to extinguish the fire. The fire was still not reported under control by 5:00 p.m.

Police and rescue crews evacuated shoppers and workers from the mall. The explosions shattered windows in buildings several hundred feet away. There are large numbers of security and rescue personnel on the scene and citizens are being kept away from the scene of the blasts.
