Shame on us (Kashmiris who talk about the rights of 84,471 sq. m) for not addressing this issue yet. Meanwhile, many thanks to activists in Pakistan and elsewhere who've highlighted this activists' detention. I think a delegation of civil society activists should arrange to meet the 'Powers That Be' in Pakistan and secure his release. Knowing this case, he will not be released without civil society intervention.
Here is a summary of his ordeal, which includes a list of notable thinkers who have joined the campaign for his release. Please also sign the petition embedded in the link below:
