Sri Lanka declared a nationwide curfew after a string of eight explosions, mostly in Colombo, left at over 200 people dead and over 450 injured on Easter Sunday, authorities said.

Xinhua news agency reported that the death toll in the multiple blasts had risen to 185 even as two fresh explosions occurred in two Colombo neighborhoods in the afternoon.

Easter Day bomb blasts at three Sri Lankan churches and three luxury hotels claimed over 180 lives, hospital and police officials said. Two other explosions followed the unprecedented string of attacks on the Sri Lankan capital.

The toll in a series of eight blasts in Sri Lanka on Sunday has risen to at least 207, with over 450 people wounded, police spokesman Ruwan Gunasekera said.

Speaking at a press conference, he said three people had been arrested in connection with the attacks that mostly targeted high-end hotels in the capital and churches where worshippers were attending Easter services.

Gunasekera said the police were investigating whether suicide bombers were involved in all of the blasts.

Defense minister said seven suspected were arrested.

Sri Lankan officials say the death toll in eight bomb blasts that struck in and just outside of the capital, Colombo, on Easter Sunday has climbed to 190, and that several suspects have been arrested.
