I understand that it is not a festive festival but a mourning time, thanks for correcting me.
But my point was it should be observed as per beliefs without worrying about security situation. Its a muslim country after all, if muslims cannot observe their religious days in a islamic country with safety then where can they do it.
Since last few days i am seeing shia muslims here beating drums, carrying a flag and collecting chanda from muslims and non muslims alike. Security is the last thing in their mind.
