GENEVA: Qatar filed a wide-ranging legal complaint at the World Trade Organization on Monday to challenge a trade boycott by Saudi Arabia, Bahrain and United Arab Emirates, Qatar´s WTO representative Ali Alwaleed al-Thani told Reuters.

By formally "requesting consultations" with the three countries, the first step in a trade dispute, Qatar triggered a 60 day deadline for them to settle the complaint or face litigation at the WTO and potential retaliatory trade sanctions.

Qatar is also raising the boycott at a meeting of the UN International Civil Aviation Organization on Monday, al-Thani said.
