Notably, the death toll in Sri Lanka has risen to 359 and the responsibility for which was claimed by the Islamic State. Prior to ISIS’ claim, Sri Lankan officials had said that the alleged attack was carried out by a little-known local jihadist group, National Thowheed Jamath, with the support of an international network.

Meanwhile, Sri Lanka has put all police stations in Colombo on high alert following reports of a lorry and van carrying explosives.

The Sri Lankan president’s office has declared a state of national emergency, which is in effect from midnight (18:30 GMT) on Monday. The emergency gives police and military extensive powers to detain and interrogate suspects without court orders. Cabinet spokesman Rajitha Senaratne had reportedly said that the Sri Lankan authorities were warned about a bomb threat from National Thowheed Jamath a full two weeks before the attacks.

Notably, a string of eight powerful blasts, including suicide attacks, struck churches and luxury hotels frequented by foreigners in Sri Lanka on Easter Sunday.
