Qatar's Emir Sheikh Tamim bin Hamad al-Thani on Sunday left a summit of Arab leaders in Tunis that had gathered the rulers of Saudi Arabia and Qatar for the first time since Riyadh and its allies imposed a boycott on Doha.

Qatar's state news agency QNA said Sheikh Tamim had departed Tunisia after attending the opening session of the Arab League summit but did not give a reason why he left the meeting.

The Tunis summit brought together the rulers of Saudi Arabia and Qatar for the first time at the same gathering since 2017 when Riyadh and its allies imposed a political and economic boycott on Doha. Saudi Arabia and its allies accuse Qatar of supporting terrorism and cosying up to Iran, an accusation Doha denies.

The leaders of Sudan and Algeria did not attend Sunday's meeting, with both nations roiled by anti-government protests.
