Colombo was hit by multiple explosions on Sunday. AFP reports that 42 people may have been killed. Reports say that foreign tourists were among the dead.

Hundreds of others were injured in the blast and taken for treatment to hospitals.

The blasts took place at the St. Anthony’s Church in Kochchikade in Colombo, the St. Sebastian’s Church in Katuwapitiya in Katana and a third in Batticaloa. At the time of the explosions, Christian faithful were praying at the churches on the occasion of Easter.

The hotels which were hit by explosions are the Shangri-La Hotel and Cinnamon Grand Hotel. Police say that the Kingsbury Hotel in the capital, too, was hit.

Unconfirmed reports suggest that two more explosions have taken place at Town Hall Red Cross building and Viharamadevi Park.
