Kolkata, March 3 (IANS): West Bengal Chief Minister Mamata Banerjee on Tuesday condemned the brutal murder of Bangladeshi-American blogger Avijit Roy in Dhaka last week.

"I strongly condemn the brutal murder of the Bangladeshi writer a few days ago. We believe in freedom of expression," Banerjee tweeted.

The Trinamool Congress supremo, who had been to Bangladesh recently, fell short of words to denounce the incident.

"Words are not enough to condemn the sad incident. My heartfelt condolences to the bereaved family of the Bangladeshi writer," she wrote.

Roy, a 42-year-old bio-engineer working in the US, was hacked to death by two attackers wielding machetes in Bangladesh capital Dhaka on February 26, when he was leaving a book fair with his wife Rafida Ahmed Banna, who was also seriously wounded in the attack.

Religious radicals had been threatening Roy over his active campaign against Islamist extremism and for strengthening secularism in Bangladesh.
