At least seven suicide bombers have been involved in a series of terrorist attacks in Sri Lanka, AP reported. 

According to the source, six blasts took place at the shrine and the Cinnamon Grand, Shangri-La and Kingsbury hotels in Colombo, as well as at two churches outside Colombo.

A total of 24 people have been detained over the attack.

According to a police statement, the death toll in the eight bomb blasts that rocked Sri Lanka has reached 290, and 500 others are injured.

The series of blasts in Sri Lanka occurred on Easter Sunday. The first six took place at three churches in capital city Colombo as well as in Negombo and Batticaloa towns and at three hotels, while the next two explosions occurred in Dehiwala and Dematagoda—two suburbs of Colombo.

Also, an improvised explosive device was discovered in close proximity to the Bandaranaike International Airport.

The main target of these attacks was the local Christians.
