The foreign ministers of Saudi Arabia, Bahrain, the UAE and Egypt are set to meet in Cairo to discuss the Qatar crisis.
The meeting of ministers, which is set to take place today, comes on the day an extended deadline expires for Qatar to accept and enact a list of demands put forward by the four Arab states.
Qatar has previously called the list of demands unrealistic and not actionable
News agency Associated Foreign Press (AFP) reported on 3 July that Qatars foreign minister, Sheikh Mohammed bin Abdulrahman Al-Thani, delivered the letter during a short visit to Kuwait, which is acting as a mediator in the crisis.
Qatar has previously denied accusations from the Saudi-led bloc that it funds terrorism, and the countrys foreign minister Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani said his country had rejected the demands, but was ready to engage in dialogue under the right conditions.
Saudi Arabia, the UAE, Bahrain and Egypt extended the deadline for Qatar to comply with a list of demands by 48 hours on 3 July. The initial deadline to accept the list of demands expired at midnight on 2 July.
Saudi Arabia and the UAE have previously said that if Qatar fails to comply with the list of demands, which include the shutting down of the state-owned Aljazeera news network, it will face further sanctions.
It is unclear what kind of sanctions Qatars Gulf neighbours will impose if it fails to agree with the demands, but there have been reports that Saudi Arabia and the UAE could restrict commercial links with countries that continue to trade with Qatar.
