RAMANATHAPURAM: After a gap of two years, thousands of devotees from India set sail on Friday to celebrate the Katchatheevu St Antony's Church festival. District collector Johnny Tom Varghese flagged off the boats from Rameswaram fishing harbour. Even though Katchatheevu was ceded to Sri Lanka in 1974, fishers from both nations retained the right to worship during the annual church festival. Special arrangements have been made at the Katchatheevu in view of the festival.
