Update  2:55 a.m. EDT April 26: Sri Lanka police said on Twitter that Mohamed Zahran, the leader of local militant group National Towheed, died in one of the nine suicide bombings Easter Sunday, The Associated Press reported. Police said they also arrested the group's second-in-command.

Update 6 p.m. EDT April 25: Sri Lanka lowered the death toll from the Easter suicide bombings by nearly one-third, to 253, as authorities hunted urgently for a least five more suspects and braced for the possibility of more attacks in the coming days.

In rolling back the number of dead from 359, a top Health Ministry official, Dr. Anil Jasinghe, said in a statement that the blasts had damaged some bodies beyond recognition, making accurate identification difficult.

Update 7:20 a.m. EDT April 24: Sri Lanka officials said 60 people have been arrested in connection with Sunday's bombings, according to The Associated Press.

A police spokesman said nine suicide bombers carried out the attacks, apparently contradicting government officials' previous statement that seven bombers were involved, the AP reported.

Ruwan Wijewardene, Sri Lanka's junior defense minister, described the attackers as educated people from upper- and middle-class households,  the AP reported.

Although authorities previously said the terror group National Towheed Jamaar was behind the attacks, Wijewardene said Wednesday that the perpetrators had split off from that group and another one called JMI, the AP reported. He did not say what the acronym stands for.

Wijewardene also amended his earlier statement that the bombings were in retaliation for the deadly mass shootings at New Zealand mosques last month, saying Wednesday that the Christchurch attacks may have been a motivation but no evidence has confirmed the link, the AP reported.
