Authorities of one of India’s richest temples have apologised after at least six pilgrims were killed in a stampede in the southern temple town of Tirupati. The devotees were waiting in queues to collect tokens from over 90 counters to offer prayers to Lord Venkateshwara Swamy on Wednesday when the incident took place, local police said.

The stampede took place on Wednesday night after thousands gathered at the Tirupati temple in the southern Andhra Pradesh state for tickets to a special festival. Visuals showed a swell of people jostling while the tickets were being distributed at counters set up by temple authorities.
