ttackers in the Bangladeshi capital Dhaka have hacked to death a US-Bangladeshi blogger whose writings on religion angered Islamist hardliners.
Avijit Roy, an atheist who advocated secularism, was attacked as he walked back from a book fair with his wife, who was also hurt in the attack.
No-one has been arrested but police say they are investigating a local Islamist group that praised the killing.
Hundreds of people gathered in Dhaka to mourn the blogger's death.
Mr Roy's family say he received threats after publishing articles promoting secular views, science and social issues on his Bengali-language blog, Mukto-mona (Free Mind).
He defended atheism in a recent Facebook post, calling it a "rational concept to oppose any unscientific and
irrational belief".
His Mukto-mona website on Friday bore the message in Bengali "we are grieving but we shall overcome" against a black background.
