Four people were killed and over a dozen injured Sunday morning in road accidents throughout Israel. In a chain collision at Lehavim Junction in the Negev, two people were killed. At least 13 others were injured, including one person who was listed in serious condition and another who was reported moderately injured. An initial investigation revealed that a trailer truck traveling from the direction of Arad rear-ended one of two school buses carrying local pupils going on a field trip. The truck then veered into the opposite lane, crashing into an oncoming car. The car was crushed, and both passengers inside were injured. Simultaneously, the school bus rammed into the bus in front of it, bringing both to a sudden stop. Several passing cars crashed into both buses and the trailer truck, and a van was pushed into oncoming traffic and flipped over. Police reported that the children were all wearing seatbelts at the time of the accident, which limited their injuries to minor ones. All the victims were evacuated to Soroka Hospital in Beersheba. In Petah Tikva, a 50-year-old pedestrian was hit by a car that veered onto a sidewalk and shortly thereafter succumbed to her injuries. The driver was arrested. In an earlier incident, motorcyclist Nadav Biton, 23, was killed in an accident on the outskirts of Afula. Police reported that Biton was not licensed to ride a motorcycle. Meanwhile, a 30-year-old French tourist was hit by a car and seriously injured while biking in Netanya. The driver, 77, initially fled the scene, police reported. After he arrived home, his wife became alarmed and contacted the police. While being questioned, the man suffered a stroke and was hospitalized in moderate condition.
