The Washington Post: Ananta Bijoy Das, a Bangladeshi writer known for advocating science and secularism, was hacked to death by masked men wielding machetes while on his way to work Tuesday morning.

Das died instantly in the attack, police in Sylhet city told the Associated Press. He is the third Bangladeshi writer to be killed in less than four months.

Though police did not offer a motive for the killing, they mentioned to Al Jazeera that Das has written about science and the evolution of the Soviet Union. He was also a blogger for Mukto-Mona, or “free mind,” the site launched by prominent author Avijit Roy, who was killed at a Bangladeshi book fair in similar fashion in February.
