Investigators in Sri Lanka have revised the death toll from the Easter Sunday atrocities to "around" 253 - more than 100 less than originally estimated.
It was previously thought 359 had died in the explosions.
Anil Jasinghe, the director general of Sri Lanka's health services, told Reuters: "It could be 250 or 260. I can't exactly say. There are so many body parts and it is difficult to give a precise figure."
Ruwan Wijewardene, Sri Lanka's deputy defence minister whose ministry is responsible for the island's police force, said the death toll had been revised down to 253 due to inaccurate figures provided by the country's morgues.
"Unfortunately the health ministry provided the earlier number to us," he said.
