Islamic State (ISIS) has claimed responsibility of serial blasts in Sri Lanka which killed over 320 people and injured more than 500 people. The Sri Lankan government has blamed the two domestic Islamist extremist groups for carrying out the attack, but they believe that it was done with the help of an international network.

Confirming the identities of 3 Indian nationals killed in the attack, External Affairs Foreign Minister Sushma Swaraj tweeted, "Indian High Commission in Colombo has conveyed that National Hospital has informed them about the death of three Indian nationals. Their names are Lokashini, Narayan Chandrashekhar and Ramesh. We are ascertaining further details."

The first explosions were reported at St Anthony's Church in Colombo and St Sebastian's Church at Katuwapitiya in the town of Negombo.
