Several ministers in the cabinet on Monday described the killing of blogger and writer Avijit Roy on the Dhaka University campus as a planned murder and feared more such deadly attacks. They also discussed the current political unrest triggered by the countrywide blockade and intermittent hartals which killed 116 people since January 5. Prime minister Sheikh Hasina chaired the weekly cabinet meeting at the secretariat. Referring to the killing of Avijit, finance minister AMA Muhith said miscreants had attacked writer Humayn Azad in a similar manner on the Dhaka University campus in February 2004. ‘It is a planned murder. They can carry out sabotage on a larger scale,’ the minister quoted Muhith to have told the meeting. Sheikh Hasina asked her cabinet colleagues and party men to be more cautious in the days ahead since there was no sign the blockade enforced by the by the BNP-led alliance would be withdrawn anytime soon. Avijit Roy, a free-thinking blogger and writer, was hacked to death by unidentified miscreants on the Dhaka University campus on the night of February 26. His wife Rafida Ahmed was grievously injured in the attack that bore extremist hallmark and was a reminder of the attack on writer Humayun Azad at the same place on a February night 11 years ago. In February 2013, blogger Ahmed Rajib Haider was also stabbed to death. The BNP-led opposition alliance called the nonstop transport blockade on January 5 to push for a fresh national poll under a non-party interim government.
