An Indian court has convicted two men, and acquitted one, on charges connected to a series of bombings 13 years ago that killed 257 people in Mumbai - formerly known as Bombay.

The court found Nasir Dhakla and Mohammed Shaikh guilty Thursday of attending conspiracy meetings and undergoing arms training in Pakistan.

But the court acquitted a third man accused of making arrangements for the bombings due to insufficient evidence. The judge in the case says prosecutors failed to prove Mohammed Mansoor was responsible for facilitating terrorist acts.

Indian authorities say the bombings were in retaliation for the destruction of a 16th century mosque, in the northern city of Ayodhya, by a Hindu mob a year earlier.

The mammoth trial began in 1994, and the latest two guilty verdicts bring the number of convictions to 28.
