Tragedy struck a preschool in the town of Kiryat Gat Sunday afternoon, when a 3-year old boy choked while playing a playground sandbox. Attempts by emergency first responders and hospital staff to resuscitate him were unsuccessful, and the boy was ultimately declared dead.

Officials say the boy apparently choked on sand which he or another child had placed in his mouth. A preschool teacher who noticed the boy exhibiting signs of distress called for emergency medical assistance.

“I got a phone call from a preschool teacher who said that one of the kids who was playing in the sandbox was feeling ill, and had told [her] that sand had gone into his mouth,” said United Hatzalah paramedic Haim Matzliah.

Matzliah, the first emergency medical responder to arrive at the scene, said the child had already passed out by the time he reached the school. MDA paramedics who treated the boy reported that he had was not breathing and had no heartbeat.

The boy was evacuated in critical condition by an MDA ambulance to Barzilai Hospital in Ashkelon, where he was pronounced dead shortly after arriving.
