Lag BaOmer London Explosion

First we had Israel flooded just prior to Pesach Sheni and now there is news of an explosion at a Jewish Lag BaOmer celebration in London.

The Daily Mail report that 30 people including children have been injured at the event in Stamford Hill, London. The story goes that they threw their mobiles onto the celebration bonfire and it is thought that caused an explosion. Many of those injured have facial burns and ten people are believed to be hospitalised. 

Not very bright are they to get that close to a bonfire with children. Seriously, where is their common sense. Common sense is more important than a bonfire, and their festival. The children are more important than a bonfire and their festival.

Seriously, why can't they turn their hearts to the children.
