THE Pakistan Muslim League (Nawaz), Awami National Party, Pakistan Tehrik-i-Insaaf and Pakistan Muslim League-F have decided to observe a day of mourning on Thursday for the victims of the fire tragedy and withdrawn their support for a strike in Sindh called by nationalist parties.

Earlier, the Muttahida Qaumi Movement had announced three days of mourning.

Some news TV channels reported late into the night that nationalist parties had decided to stick to their decision of observing the strike.
