Mumbai blasts: Investigators trying to connect the dots between Mumbai's three serial blasts and the people behind them have run into another roadblock. The security camera footage from Opera House, where one of the blasts took place, had supposedly provided important leads.

The three bombs that shook Mumbai on Wednesday were Improvised Explosive Devices (IEDs), prepared with a deadly mixture of ammonium nitrate, Tri-Nitrate Toluene (TNT) and fuel oil. Ball bearings were used as shrapnel and smart cellphones as timers.

The early consensus seems to be that the blast was planned by the Lashkar-e-Toiba (LeT) and its off-spring, the Indian Mujahideen (IM), created by the LeT in 2005.
