A Sri Lankan province north of the capital was under indefinite curfew on Tuesday after the first death in anti-Muslim riots in the wake of the Easter terror attacks, police said.
A nationwide night curfew was relaxed in all areas except the North-Western Province (NWP) where a Muslim man was killed by a mob on Monday, police said, in a violent backlash against last month's bombings.
The attacks came during the Muslim holy fasting month of Ramadan. A state of emergency has been in place since the bombings -- which the Islamic State group claims to have helped -- and security forces have been given sweeping powers to detain suspects.
The latest wave of unrest started when a mob targeted Muslim-owned shops in the town of Chilaw, 80 kilometres (50 miles) north of Colombo, on Sunday in anger at a Facebook post by a shopkeeper.
