Hadar Yaakovi, 13, from Kiryat Ata, was killed when her father's car overturned on Route 6 around noon. He mother was gravely injured. According to police, the father lost control over the Hyundai for reasons not yet clear, driving for a few hundred meters on road's shoulder. No skid marks were found. After turning, the car rolled over several times before coming to a rest on its roof.

Her mother was taken in serious condition to Beilinson Hospital in Petah Tikva, and her father and another friend who was in the car suffered light to medium injuries.

The father, a policeman, at first refused to be taken to the hospital after realizing his daughter had been killed. The family was traveling to an elder's son graduation ceremony from a paramedics' course in the Israel Defense Forces. Hadar Yaakovi's funeral will take place today at the Kiryat Ata Cemetery at 1 P.M.

In another accident, a resident of the northern border village of Arab Al Aramsha was killed when the tractor he was driving overturned. He suffered a fatal head injury and died at the scene.

In the south, two residents of Tarkumiyeh were killed when their car rammed into a tree near Sderot. Police said the vehicle spun into a roadside ditch after hitting the tree, and the two men, who were in their 40s, were trapped in the car for some time. They were pronounced dead at the scene.

Later in the day, three children aged 11 and 12 from the village of Peki'in were injured in a hit-and-run accident. Two of them were taken by helicopter to Haifa's Rambam Medical Center, where the condition of one was described as serious and of the other as life-threatening. Police said the three were standing on a main road of the village when a vehicle hit them and continued driving.

Although the road has busy traffic throughout the day, police said they did not rule out the possibility the driver was a local resident, who fled after being frightened by the accident. Police were using a helicopter yesterday to search for the offending vehicle, and have appealed to eyewitnesses to come forward.
