Colombo: The Sri Lankan authorities on Monday enforced a six-hour countrywide curfew as communal violence continued to spread in the island nation in the latest fallout from the Easter Sunday suicide bombings, which killed nearly 260 people. “The curfew has been imposed from 9 p.m. tonight to 4 a.m. tomorrow,” a police spokesperson said. Earlier in the day, the police reimposed a curfew, few hours after it was lifted, on four towns of Kuliyapitiya, Bingiriya, Dummalasuriya and Hettipola in the north western region till 4 a.m. tomorrow following a communal clash in the area.

Prime Minister Ranil Wickremesinghe also appealed for calm after the unrest broke out, especially in Kurunegala district targeting Muslims, and appealed to the public not to be swayed by false information. “I appeal to all citizens to remain calm and not be swayed by false information. Security forces are working tirelessly to apprehend terrorists and ensure the security of the country, but each time there is civil unrest, we increase their burden and hamper ongoing investigations,” he said.

The blockade of Facebook and WhatsApp comes a day after Sri Lankan police imposed curfew in the country’s western coastal town of Chilaw where a mob attacked a mosque and some shops owned by Muslims in a dispute that started on a Facebook post by a Muslim shop owner. The violence is a new backlash from the Easter attacks where nine suicide bombers, including a woman, carried out a series of devastating blasts that tore through three churches and three luxury hotels, killing 253 people and injuring over 500 others. The Islamic State terror group claimed the attacks, but the government blamed local Islamist extremist group (NTJ).
