"We are speechless. He was demanding justice for killing of other bloggers," said Imran Sarker, head of a network of activists and bloggers. "Who will be next for demanding justice for Niloy?"
Mr Das wrote blogs for Mukto-Mona, a website once moderated by Avijit Roy, himself hacked to death in February...
Sara Hossain, a lawyer and human rights activist in Dhaka, has told the BBC Mr Das and Mr Roy were on a list of targets. "They've always believed and written very vocally in support of free expression and they've very explicitly written about not following any religion themselves," she told the BBC World Service's Newsday programme. "These last two have been part of a blog called Mukto-Mona (Free Mind), which is about free thinking and is about explicitly taking on religious fundamentalism and particularly Islamic religious fundamentalism. Their names have been on lists of identified targets."
Today, we state clearly that considering apostasy to be a criminal offense in state level in fact is an inexcusable offense. If being religious is someone’s right, then being critical to religion is also one’s right. There is nothing wrong to be critical to any idea or ideology, as CFI aptly put on its Blasphemy day banner – ‘Ideas do not need rights, People do’!So wrote Avijit Roy on his blog Mukto Mona, on September 30, 2013.

Detection equipment was sent in and they saw a woman waving her hand. She shouted "I'm still here" and said her name was Reshma....
Rescuers said it was possible that the woman survived because of the large quantities of oxygen and water that were pumped into the ruins in the early stages of the rescue effort.
Rescuers tunneling Friday into the rubble of the eight-story building that collapsed Wednesday discovered another 50 people trapped on what remained of its third floor.... Also Friday, two women who gave birth under the debris were rescued -- along with their infants....
Officials coordinating the operation have said the rescue efforts would end Saturday morning, when heavy equipment will be used to retrieve the remaining bodies and cart away the rubble.... The planned use of heavy equipment ignited protests from the people who crowded near the rescue site, many of them relatives who were showing pictures of the missing to whomever would pay attention and saying they did not believe 72 hours was long enough to wait.
When the state of Pakistan was formed in 1947, its two regions, East Pakistan (also called East Bengal) and West Pakistan, were split along cultural, geographical, and linguistic lines. In 1948, the Government of Pakistan ordained Urdu as the sole national language, sparking extensive protests among the Bengali-speaking majority of East Pakistan.Would East and West Pakistan be one country today if the government hadn't been so hardcore about Urdu?
