Indian Prime Minister Manmohan Singh says public support for peace with Pakistan could suffer if there are more attacks like Tuesday's assault on a disputed religious site in Ayodhya.
Mr. Singh made the comments to reporters as he traveled to the G-8 summit in Scotland.
Security forces in northern Uttar Pradesh state killed six unidentified gunmen who attacked a religious site claimed by both Hindus and Muslims.
The attack on the makeshift Hindu temple in Ayodhya sparked protests in dozens of Indian cities.
While no one has claimed responsibility for the attack, Hindu nationalists blame Islamic militants, who they say are backed by Pakistan. Pakistan has condemned the attack, and India's prime minister has appealed for calm.
