Blogger killed in Bangladesh, three others wounded, police say

Dhaka, Bangladesh (CNN)Another secular blogger was hacked to death and three other people were severely wounded in two separate attacks in Bangladesh's capital on Saturday, Dhaka police said.

Publisher and secular blogger Faisal Arefin Dipan was killed in Shahbagh area while three others, also publishers and bloggers, were hacked and shot in Lalmatia area.

Muntasirul Islam, a deputy commissioner and spokesman of Dhaka Metropolitan Police told journalists that unidentified assailants were involved in the attacks.

Al-Qaeda in the Indian Subcontinent, or AQIS,
claimed responsibility for the assaults, saying Dipan and the others made derogatory remarks about the Muslim faith.

Writer Ranadipam Basuis was one of three people who were severely wounded in two separate attacks against secular writers and publishers.

The attackers struck inside publishing houses where the men worked, the spokesman said.

"It's been seemed pre-planned and (an) act of terror,"

Islam said, adding that police were yet to make any arrests.

Both Dipon and Ahmedur Rashid Tutul, who was being treated at Dhaka Medical College Hospital, published books of slain Bangladesh-born American blogger and writer Avijit Roy.

Roy was murdered in a similar attack in an annual book fair on Dhaka University campus in February.

A month later, Washiqur Rahman, 27, was savaged by two men with knives and meat cleavers just outside his house as he headed to work at a travel agency in the capital.
