The fake statement mentioned a number of sensitive issues including Iran's role in the region, Islamist groups Hamas and Hizballah, and the US President Donald Trump.



Qatar denied the statement attributed to the emir.



Trump visited Riyadh last weekend for his first foreign tour as president, where he attended a Saudi-organised Arab-Muslim-US summit and announced a huge arms deal with Saudi Arabia.



Saudi Arabia and the UAE have had a rocky relationship with Qatar in recent years with Riyadh and Abu Dhabi briefly pulling their ambassadors from Doha in 2014.



Last week, Qatar said it was the target of a smear campaign by a number of media outlets.
