Explosion in Stamford Hill: Bonfire 'erupted like a bomb' after mobile phone was thrown onto it,

Explosion in Stamford Hill: A street bonfire to celebrate a Jewish holiday erupted “like a bomb” leaving 10 people injured, shocked witnesses said.

Seven of the injured were taken to hospital after the blast sent a fireball into the crowd at the Lag BaOmer event in Stamford Hill last night.

Witnesses said children were among those hit outside a synagogue. Video footage shows members of the community standing around the bonfire as it exploded moments after being lit with a torch.

The fire is traditionally made from cotton wool soaked in olive oil. It has been claimed locally that some children had poured petrol or another accelerant onto it before it was lit.

Witnesses claimed the explosion happened after a rabbi threw a mobile phone on to the fire having given a speech warning about the dangers of smartphones and the negative impact on young minds.

Rabbi Osher Shapiro was at the front of the crowd when it was being lit. He said: “He [the local rabbi] did put a smartphone on the bonfire. It is wrong to suggest that it caused the problem. The phone did not cause the explosion. It went up very fast. It was just a metal frame covered in cotton wool and olive oil.

“There were hundreds of children there and a lot of them were at the front to get a better view. Luckily there were barriers. Without those, the injuries could have been worse.”

Rabbi Shapiro added: “Putting the phone on the fire is symbolic to show the negative impact they can have on young people.”

Paramedics arrived in Ravensdale Road just before 9.30pm and treated 10 people at the scene. Those taken to hospital suffered minor burns and injuries. Hatzola, a Jewish volunteer emergency medical service, said it provided a “mega response team” and said “multiple patients were treated” at the scene.

Rachel Szwarc was at the event with her children aged four, six and eight. She said: “It went off like a bomb, people were screaming and shouting and tearing off their clothes because they were on fire. Everyone was trying to find their children.

“The children were all at the front to get a better view so they were the ones worst hit. My six-year-old had been at the front but luckily we went towards the back just before the fire was lit. We could see people with burns, it was very shocking.”

Community leader David Klein said seven children had been taken to hospital and all had been discharged. Organisers said that the phone thrown on to the fire did not have a battery. Lag BaOmer is a festive day corresponding to the date of the death of Rabbi Shimon bar Yochai.
