Ayodhya, India - A report on the 1992 demolition of the Babri Masjid mosque, which sparked nationwide communal riots, has been submitted to the Indian government.
The Liberhan commission was set up to investigate the events that led to a Hindu mob tearing down the disputed mosque in the town of Ayodhya.
The commission has taken 17 years to complete its investigation, which cost more than 65m rupees ($1.3m).
The contents of the report have not yet been made public.
The site of the 16th Century Babri Masjid mosque in the northern Indian town of Ayodhya had been a focus for Hindu-Muslim hostility for decades.
On 6 December 1992 a mob of Hindu militants tore down the mosque, sparking nationwide communal riots. The rioters claimed the site used to be a temple marking the birthplace of a popular Hindu god.
The BBC's Rahul Tandon in Delhi says that the destruction of the mosque was one of the most controversial moments in Indian history and more than 2,000 people died in violence between Hindus and Muslims following its demolition.
The Liberhan commission was set up within days of the incident. It has held over 4,000 sittings and the last witness was interviewed in 2005.
With 48 extensions to its mandate, it has become India's longest-serving inquiry.
Senior figures from the main Indian opposition party the BJP - including the former deputy Prime Minister LK Advani appeared before it.
Justice Liberhan has blamed "the uncooperative attitude of some people" for the delay in the report.
Our correspondent says that the commission's findings will have important political implications, particularly for the BJP who were in Government in Uttar Pradesh when the mosque was demolished.
The report is likely to be presented to parliament at a later stage.
