A baby boy slipped into unconsciousness during a circumcision ceremony and was taken to hospital in a critical condition on Thursday.

The eight-day-old infant underwent the brit milah ritual at the Pinhas Lavon synagogue in Holon when he stopped breathing and lost pulse.

The family made desperate calls to Magen David Adom for an ambulance and to the Hazalah first response organization.

Medic Yehuda Mizrahi was first to arrive on the scene.

“When I arrived, the baby was completely blue, not breathing and with no pulse,” he told Channel 2, and described how he began resuscitation techniques, including massages to try to restart the boy’s vital systems. Finally an ambulance arrived and the infant was rushed to Wolfson hospital.

Doctors began investigating what might have caused the incident, including excessive blood loss, a congenital disease, or infection.
