Qatar diplomatic crisis
diplomatic crisis between several Arab League countries and Qatar

The Qatar diplomatic crisis was a deterioration of relations between Qatar and four Arab states between 2017 and 2021. It began when Saudi Arabia, the United Arab Emirates, Bahrain, and Egypt simultaneously severed their bilateral relations with Qatar and subsequently banned Qatar-registered aircraft and Qatari ships from utilizing their sovereign territory on air, land, and sea. This involved Saudi Arabia's closure of Qatar's only land crossing, initiating a de facto blockade of the country. The crisis was brought to an end in January 2021, following an agreement between the Saudis and the Qataris.
The Saudi-led coalition cited Qatar's alleged support for terrorism as the main reason for their actions, alleging that Qatar had violated a 2014 agreement with the members of the Gulf Cooperation Council (GCC), of which Qatar is a member. Saudi Arabia and other countries have criticized Al Jazeera and Qatar's relations with Iran. Qatar explained that it had provided assistance to some opposition groups, including Islamist groups (such as the Muslim Brotherhood), but consistently denied aiding militant groups linked to al-Qaeda or the Islamic State of Iraq and the Levant (ISIL). Qatar also emphasized that it had long assisted the United States in the war on terror, especially via the Qatar-based Al Udeid US military base, and through the ongoing military intervention against ISIL.
One day into the crisis, the Saudi-led coalition was joined by Jordan, and was further supported thereafter by the Maldives, Mauritania, Senegal, Djibouti, the Comoros, and the Tobruk-based government in Libya, all of which severed relations with Qatar. The demands against Qatar included reducing diplomatic relations with Iran, stopping military coordination with Turkey, and closing Al Jazeera; Qatar refused to agree to any of the Saudi-led coalition's demands. Initial supply disruptions were minimised by additional imports from Iran, with which Qatar restored full diplomatic relations in August 2017, and Turkey.
