I can only laugh at these Shia pilgrims coming back from Iran complaining now.
The government explicitly asked them not to go to Iran and it was well known that there is an epidemic going on in Iran and if they had common sense, should not have gone to Iran in the first place.
Iran gets foreign revenue through these pilgrims, Pakistan gets nothing, but they are and will remain Pakistan's problem.
Only if they had some common sense, none of this had happened and the virus they brought to Pakistan is their fault and only theirs.
