Kar sevaks pull down the domes of Babri Masjid on December 6, 1992.

The Liberhan Commisison, which was formed 10 days after Babri Masjid was demolished, submitted its probe report to then Prime Minister Manmohan Singh on June 30, 2009.

The commission, led by Manmohan Singh Liberhan, was tasked with investigating the sequence of events leading to the destruction of the 16th century mosque in Ayodhya by kar sevaks.

According to the Liberhan Commission report, the security apparatus was non-existent and the police ineffective when nearly 5,000 kar sevaks pulled down the domes of Babri Masjid on December 6, 1992.

The commission's report puts the number of kar sevaks present in and around Ayodhya during Babri demolition at 75,000 to 1.5 lakh.

Against this, forces deployed in and around Ayodhya included 35 companies of Provincial Armed Constabulary (PAC), 195 companies of paramilitary forces, four companies of CRPF, 15 tear gas squads, 15 police inspectors, 30 police sub-inspectors and 2,300 police constables.

As per the Liberhan Commission report, this is what happened on December 6, 1992:

10:30 AM: L K Advani, Murli Manohar Joshi, and other leaders along with sadhus reach the platform for the symbolic kar seva. They stay there for 20 minutes and go to Ram Katha Kunj where religious leaders had been making speeches.

12 PM: A teenage kar sevak breaches the other cordon around the structure and climbs the dome. Around 150 kar sevaks follow him and storm the structure wielding pickaxes, hammers, shovels and iron rods.

12:15 PM: Nearly 5,000 kar sevaks begin assault on the dome. Advani, Joshi, Ashok Singhal and Vijayaraje Scindia request them to come down from the structure. No one listens to them.

12:30 PM: Kar sevaks hurl bricks at security forces, attack media. District magistrate asks for paramilitary forces stationed around Ayodhya. Kalyan Singh (then Uttar Pradesh chief minister) agrees to deployment on condition they do not fire.
