A prominent Bangladeshi-American blogger has been hacked to death in the street by militant Muslims after denouncing religious extremism.
Dr Avijit Roy, who lives in Atlanta, Georgia, and is known for his outspoken atheism, was jumped by the gang of machete-wielding assailants last night Dhaka, the capital of Bangladesh.
An obscure militant group, Ansar Bangla 7, has claimed responsibility for the attack, which it said is in retaliation for his 'crime against Islam'.
They also said he was singled out because he is a U.S. citizen, and characterized the vicious killing as 'revenge' for attacks on ISIS in Syria.
Police said at least two men attacked Roy landing three strong, deliberate blows to the right side of his head.
They turned on his wife, Rafida Ahmed, when she tried to save him, then fled into the crowd.
His body was found in a pool of blood on Thursday night after the brutal attack.
Ahmed, 45, is also a blogger. She is reportedly now in hospital with a deep cut to her head.
Roy, who is a naturalized U.S. citizen and also a bio-engineer, had been receiving death threats online for years.
