NEW YORK, April 27: Bangladeshi authorities should immediately investigate the killings of two lesbian, gay, bisexual, and transgender (LGBT) human rights activists, Human Rights Watch said. Police found Xulhaz Mann and Tonoy Mahbub hacked to death in a Dhaka apartment on the evening of April 25. The killings follow a spate of recent targeted attacks on writers, educators, bloggers and editors who promote liberal and secular ideas that radical groups believe are against Islam. The killings of Mann and Mahbub brings to nine the number of liberals hacked to death in Bangladesh in 2016. (IANS)
