London Explosion: 30 Injured In Stamford Hill

The Yeshiva World website reported that spectators fled in "shrieks and panic" after the blast.

Hatzola, a volunteer emergency medical service, said it provided a "mega response team" at the festival.

Ten people were previously confirmed as being injured when a bonfire lit to celebrate the eve of a Jewish holiday exploded and sent a fireball into a crowd in north London but the number went up to about 30.

Around 30 people have been injured at a Jewish festival after a small explosion when the fire was lit. Some reports suggest that mobile phones that had been thrown onto the fire had exploded during the celebrations. The devices were put onto the flames at Stamford Hill, north east London, for Lag BaOmer ‘as a warning against the evil of smartphones’. However, the blast only happened as the fire was being lit, suggesting that it was caused by fumes from the fuel on the fire, believed to be oil.

Paramedics were called to the Lag BaOmer event in Stamford Hill on Wednesday evening.

Video posted to the internet showed dozens of people standing around the bonfire, which was reportedly soaked in oil.

As soon as a torch was used to light the bonfire, there was an explosion that sent crowds running.

Other reports said that at least one mobile phone had been put into the fire.

A spokesman said that "multiple patients were treated" at the scene, in Ravensdale Road.

The Metropolitan Police said 10 people suffered minor injuries, adding that no criminal allegations had been reported.

Some of those hurt are said to have suffered facial burns.

London Fire Brigade said it had responded to several bonfires throughout the night.
