Father, two brothers of Sri Lanka blasts mastermind killed in gun battle

The father and two brothers of the suspected mastermind of Sri Lanka's Easter Sunday bombings were killed when security forces stormed their safe house two days ago, police sources and a relative of the suicide bombers told Reuters on Sunday.

Zainee Hashim, Rilwan Hashim and their father Mohamed Hashim, who were seen in a video circulating on social media calling for all-out war against non believers, were among 15 killed in a fierce gun battle with the military on the east coast on Friday, four police sources said.

Niyaz Sharif, the brother-in-law of Zahran Hashim, the suspected ringleader of the wave of Easter Sunday bombings that killed over 250 people in churches and hotels across the island nation, told Reuters the video showed Zahran Hashim's two brothers and father.

Three of the 15 people killed were the same people who were seen in the undated video on social media, in which they discus martyrdom and urge their followers to kill all non believers, police sources said.

Sri Lanka has been on high alert since the attacks on Easter Sunday, with nearly 10,000 soldiers deployed across the island to carry out searches and hunt down members of two local Islamist groups believed to have carried out the attack.
