At least 290 have been reported dead and 450 wounded after 3 churches and 3 hotels were hit by explosions Sunday in Sri Lanka.

According to Reuters, the 3 hotels hit in the capital Colombo, were the Shangri-La, Kingsbury Hotel and Cinnamon Grand.

According to The Guardian, the 3 churches hit by blasts are St Anthony’s Church in the capital, St Sebastian’s in Katuwapitiya, north of Colombo, and local media has also reported a church in Batticaloa in Eastern Province was hit.

The six explosions took place as the Christian world celebrates Easter on Sunday, and happened almost simultaneously. At least two are suspected to have been carried out by suicide bombers.

Nobody has yet claimed responsibility for the explosions, according to Reuters, but local reports have claimed that ISIS is behind the attacks.
