Prime Minister warns those setting or inciting fires will be treated as terrorists
Israeli police have arrested 12 people on suspicion of arson and inciting to deliberately start fires, The Times of Israel reported on Friday.
Arrests have been made in connection with forest fires raging in Haifa and the West Bank for the third consecutive day.
Massive wildfires have already destroyed hundreds of homes and forced the evacuation of some 80,000 people.
Firefighters continued to fight the flames on wooded hills around Jerusalem and in northern areas on Friday, with support from Palestinian firemen and emergency teams from Greece, Cyprus, Croatia, Italy, Russia and Turkey.
Israeli Prime Minister Benjamin Netanyahu warned that those setting or inciting fires will be treated as terrorists.
Local news outlets reported on Thursday referring to the police that arson was behind at least 60 percent of the fires that continue to rage across the country.
The fires are the largest in the country since the December 2010 bushfire in northern Israel, in which 44 people were killed. Investigators concluded at the time that that blaze was caused by negligence.
