A research scholar at the Aligarh Muslim University, or AMU, who had taken a break to go home has joined the terror group Hizbul Mujahideen, a development that is seen as a setback to government efforts to persuade young Kashmiris to give up violence and return to the mainstream. The police made the discovery after Mannan Bashir Wani's photograph, holding what appeared to be a AK assault rifle, appeared on social media on Sunday.
