Sri Lanka vows to go tough on anti-Muslim rioters

Sri Lanka has partially lifted an overnight curfew imposed nationwide after the worst bout of anti-Muslim violence since the deadly Easter Sunday bombings.

Mosques and Muslim-owned shops have been vandalized or set on fire, and one Muslim man has been slashed to death.

Police say a curfew will remain in the north-western province until further notice.

In several towns, police fired into the air and used tear gas to disperse mobs.

Tensions have heighten since Islamist militants attacked churches and hotels three weeks ago on Easter Sunday, killing more than 250 people.
