MEGADIM, Israel (AP)-The worst forest fire in Israel's history on Thursday destroyed one of the country's few forested areas, killing at least 36 guards on their way to rescue prisoners there, destroying homes and forcing the evacuation   of thousands. The fire ran through the Carmel forest in Israel's Galilee, reaching the coastal city of Haifa, jumping from place to place in the forest. The fire broke out around midday and quickly spread and was still burning out of control as midnight approached. Investigators   supposed that the fire could have been set accidentally, or it might have been a criminal act, but pretty much ruled out   some sort of attack by a Palestinian group. "This is a huge disaster," Prime Minister Benjamin Netanyahu said. "The government is using all means to control the fire." He said some countries such as Cyprus, Italy, Russia and Greece agreed to provide backup. Most of the dead were Prison Service guards racing through the fire toward a prison to evacuate the prisoners, most of them Palestinians. A tree fell across the road, blocking their bus. Some guards were burned alive inside, while others died as they tried to escape. Fourteen bodies were found near the burnt bus 10 hours after the fire started. The fire heavily damaged one of Israel's few large forests, made up of natural growth and planted areas, a favorite place for camping and a home for dozens of species of wildlife. Forestry workers tried to evacuate animals from the fire. The forest recovered slowly from a fire in 1989, but experts said Thursday's big fire was many times worse. The text is mainly about   _  .
