Indeed, Bahraini shia hates Pakistanis, but this feeling is shared among all shias of the region, be it Afghani, Irani, Pakistani or even Saudi shia, but it's wrong assertion that Bahrain police hurt any local or foreign shia.
Bahrain's violence of 2011 was curbed by Saudi Army, not by hand full of Pakistanis employed in Bahrain police about 50 years ago, actually most of those are now Bahraini nationals and living retired life... may be this is what enemies of Bahrain are exploiting.
Last but not least, i have no problem with you or Iranian flag, so no need to do 'hawai fire' let me know when i state any thing beyond fact !!!
