DOHA - Five Arab states, including Saudi Arabia, the UAE and Egypt, pulled their ambassadors and suspended flights to Qatar on Monday in an escalating diplomatic crisis.
Qatar has for years been accused of being too lax with financial restrictions against extremists in the region. Here are some of the key accusations against Doha, a regional ally of the United States.
Muslim Brotherhood, Hamas, Taliban
Since Qatar's rise in international politics in the late 1990s, the gas-rich emirate has directly and indirectly supported Islamist groups across the Arab world, including Egypt's Muslim Brotherhood and allies of the Brotherhood in Tunisia and Libya.
The kingdom was a key backer of Egypt's Islamist ex-president Mohammed Morsi, sparking a 2014 diplomatic dispute that led Saudi Arabia, the UAE and Bahrain to temporarily recall their ambassadors.
