Doha — Qatar has filed a complaint with the World Trade Organisation (WTO) over an "illegal siege" imposed by its Gulf neighbours, its commerce ministry said on Monday. The gas-rich emirate has been slapped with sanctions and demands after four countries, including regional kingpin Saudi Arabia, cut ties with it on June 5, accusing Doha of fostering Islamist groups and of links to Riyadh’s arch-rival Iran. Qatar denies the allegations. The ministry of economy and commerce said a complaint had been lodged with the WTO’s dispute settlement body against the "siege countries".
