The trial has begun in India's commercial capital, Mumbai (Bombay) of 13 people accused of carrying out the bombing of local trains in July 2006.

A total of 187 commuters were killed and more than 700 people wounded in the seven co-ordinated blasts on the city's train network during rush hour.

Police in Mumbai have said they believe the bombings were carried out by a group linked to the Pakistani-based militant group, Lashkar-e-Toiba (LeT).

Pakistan rejects the allegations.

It says India produced no evidence of Pakistani involvement in the attacks.
