A Hindu trust in India's eastern state of Bihar has begun building a replica of Cambodia's Angkor Wat temple, BBC News reported.

A foundation-laying ceremony for the $20m (£12.5m) project has been held 25km (16 miles) from Bihar's capital Patna, on the banks of the Ganges.

The builders say the result will be the world's largest Hindu temple. The Mahavir Mandir Trust says construction will take 10 years. The temple will be constructed on a sprawling 40-acre site in Vaishali district in north Bihar.

The main temple of the Unesco-listed Angkor Wat was originally Hindu when built in the 12th Century but was later used for Buddhist worship.
