MQM members go to India, particularly Delhi. It's relatively easier for urdu speaking muhajirs to go to India for a lot of them have relatives there, compared to other ethnic groups. Some Karachi and Lahore based muhajirs go to India every year.
In case of this guy, he got training in Afghanistan. According to this archived report from bbc(I think), during the 90s, a lot of hardcore terrorists from MQM went to Afghanistan in Northern Alliance controlled territory to get training and sometimes, asylum. I imagine they went to Afghanistan to get training from Raw agents stationed there to help the Northern Alliance. And this guy is "Nadeem Commando" I think. He was a well known terrorist during the 90s.
He cited the JIT report. He didn't make it up. And don't you forget, India's daughters star in pornographic "blue films" as well. Not to mention, that you guys have a red light district in every major city. I'm not sure what you're getting so upset about. Do you deny that loose women exist in India?
Sure the JIT report makers are lying... Now you Indians will claim that even the first cadre of Tamil Tigers was not trained in the jungles of Madhya Pradesh.
