Pakistan's Punjab province has placed restrictions on movement of wheat and flour supplies to Khyber Pakhtunkhwa (KP) and Sindh provinces. The move, which has been called unconstitutional, has threatened food availability and destabilised market prices in KP. PPP Sindh President Nisar Khuhro said Punjab's actions are a "grave injustice" and economic exploitation of Sindh's farmers and labourers.
