More than 137 people have been killed and 560 more injured in a string of bomb attacks on hotels and churches as worshippers attended Easter services.
Americans, British and Dutch citizens were among dozens of foreigners killed.
At least seven blasts have been reported, three at hotels and three at churches, with the first taking place at St Anthony’s Church in Colombo and St Sebastian’s in the town of Negombo just outside the capital.
Shortly after those blasts were reported, police confirmed three hotels, the Shangri-La, Cinnamon Grand and Kingsbury hotels, in the capital had also been hit, along with a church in the town of Batticalao, in the east of the country.
The Foreign Office said it was “urgently seeking” information from authorities in Sri Lanka.
