KARACHI- After suffering from load shedding, water shortage and lawlessness, the people of Karachi are facing flour crisis these days. The flour shortage intensified today as the strike of the Flour Mills Association entered into the fifth day. Few days ago, Sindh flour mills owners had threatened to go on a strike. They demanded the wheat support price in the province to be brought at par with that of Punjab. Millers said all factories will be closed tomorrow if their demands are not fulfilled.
