Qatar's Emir Sheikh Tamim bin Hamad al-Thani has received an invite from Saudi Arabia to attend this month's Gulf Cooperation Council summit, despite an ongoing diplomatic crisis, Doha state media has said.
The tweet did not say if the emir would travel to the Kingdom.
Regional powerhouse Saudi and its allies the United Arab Emirates, Bahrain and Egypt have suspended all relations with Qatar, claiming Doha supports terrorism and is too close to Riyadh's great rival, Iran.
Qatar denies the allegations, but the bitter dispute has dragged on for 18 months and has shown little sign of being resolved.
