Re: MQM calls for people arrested by rangers to be released
Ohhh … and all this was happening while I was alive, fully grown up, even lived in Pakistan for several years during 90s, and still never heard or read of what you are claiming … how mysterious?
Or … is your claim a line from your imaginary Novel? 
Bhai, how old are you?
Well, what I know is that a Shia militant group was and probably even active today is doing targeted Killing of some prominent activists belonging to Deobandi sect who were killing Shias (as well as Sunnis), that is all.
As for relationship between Shia and Sunni (Berelvi), then (in 90s), earlier than 90s, as well as today, both communities were not only living together peacefully but were taking part together in most religious related events, such as Eid-e-Milad-ul-Nabi and Muharram (both events I mentioned do not belong to Shia or Sunni, but to both Shia and Sunni).
Actually, both Shias and Sunnis are getting targeted with bombs and Suicide attack in Mosques and other religious gatherings by terrorists groups belonging to Deobandi sect, calling one (Shia) Kafir and other (Sunni) Biddati … something that has not decreased but increased after 9/11, once Taliban (another Deobandi outfit) joined in.
What I know, most bomb and Suicide attacks by these terrorists on mass gathering of Shias and Sunnis happened after 9/11, not in 90s … as before 9/11 when Taliban elements did not joined in, most attacks by these Kharjee terrorists in Pakistan were target killings.
