Being an atheist in Pakistan can be life-threatening. But behind closed doors, non-believers are getting together to support one another. How do they survive in a nation where blasphemy carries a death sentence?
Omar, named after one of Islam's most revered caliphs, has rejected the faith of his forefathers. He is one of the founding members of an online group - a meeting point for the atheists of Pakistan.
But even there he must stay on his guard. Members use fake identities.
"You have to be careful who you are befriending," he says.
One man contacted Omar to say he had visited his Facebook profile and printed out pictures of him with his family. "You cannot be safe," Omar says.
In Pakistan, posting about atheism online can have serious consequences.
Under a recently passed cyber-crime law, it is now illegal to post content online - even in a private forum - that could be deemed blasphemous. [BBC] Read more
