A Muslim man was reportedly slashed to death in Sri Lanka on Monday, making him the first fatality in a violent new backlash against the Easter attacks.
The 45-year-old man died shortly after admission to a hospital in Puttalam district during anti-Muslim rioting, police told AFP news agency.
Police imposed the island-wide curfew from 9pm local time (15:30 GMT) to 4am, a police statement.
Officials told AFP the curfew was aimed at preventing an escalation of violence, after a second day of anti-Muslim riots in the country.
Curfews were previously limited to specific areas where attacks had taken place, including Puttalam, Kurunegala and Gamphala districts near Colombo.
