Seven blasts hit Mumbai's busy commuter network

The men are accused of plotting and carrying out the bombings. They deny the charges, but say they do not recognise the Mumbai court's authority.

Police say they are trying to trace 15 other suspects, most of whom are thought to be Pakistani nationals.

Seven blasts ripped through trains in the evening rush hour on 11 July 2006.

The co-ordinated explosions were detonated within 15 minutes of each other.

The men face several charges, including conspiring to use explosives to cause large scale loss of life.

Reading the charges, Judge Mrudula Bhatkar said they had instigated young Muslims "in the name of religion to resort to terrorist acts", the Associated Press reported.

And they are accused of belonging to the Pakistani-based militant group Lashkar-e-Toiba (LeT), which fights against Indian control in Kashmir.

Pakistan rejects any involvement in the attacks.
