On Saturday, unknown assailants hacked Faisal Arefin Dipan of Jagriti Prokashani to death and critically injured Shuddhoswar's Ahmedur Rashid Tutul and bloggers Tareque Rahim and Ranadipam Basu.

Dipan and Tutul were publishers of slain secularist writer-blogger Avijit Roy who was also hacked to death near the TSC at Dhaka University on February 26.

Soon after the attacks, a group identifying itself as "Ansar Al Islam (AQIS) Bangladesh," claimed responsibility for the twin incidents through an email sent to different media outlets.
