NEW DELHI :
An explosion was reported on Monday near a church in the Sri Lankan capital Colombo where a day earlier almost 300 people were killed in eight serial blasts.
The explosion on Monday came as police were trying to defuse a bomb found near the St Anthony's shrine, one of three churches targeted by suicide bombers on Sunday. Other targets of the suicide attackers included at least three luxury hotels besides a guest house.
The Sri Lankan government has blamed a little-known local jihadist group, National Thowheed Jamath, although no-one has yet admitted carrying out the attacks. Some 500 people were injured in the suicide attacks on churches and hotels.
There was no immediate information on injuries in Monday's blast, or how large it was, AFP news agency reported.
Other news reports said Sri Lankan authorities had discovered 87 detonators near a bus station.
President Maithripala Sirisena has imposed a national emergency in the wake of the attacks.
