Local police have told CNN today that the Easter Sunday bombings have claimed the lives of 310 people.
The number is a significant increase on the previously reported death toll.
Police Media Spokesperson SP Ruwan Gunasejara had no further updates on the people injured but previous estimates indicated at least 500 people were injured in the blasts across the three churches and several high-end hotels.
Sri Lankan officials failed to heed warnings from intelligence agencies about the threat of an attack by a domestic radical Muslim group that officials blame for Easter Sunday bombings which killed more than 200 people, the country's health minister said today.
The coordinated bombings that ripped through churches and luxury hotels were carried out by seven suicide bombers from a militant group named National Thowfeek Jamaath, Health Minister Rajitha Senaratne said.
International intelligence agencies warned of the attacks several times starting April 4, Senaratne said.
On April 9, the defence ministry wrote to the police chief with intelligence that included the group's name, he said.
On April 11, police wrote to the heads of security of the judiciary and diplomatic security division, Senaratne said.
It was not immediately clear what action, if any, was taken in response.
Authorities said little was known about the group except that its name had appeared in intelligence reports.
