There will be no negotiations over demands by Saudi Arabia and other boycotting nations for Qatar to stop supporting terrorism, reported state news agency Wam, citing the Saudi Foreign Minister Adel Al Jubeir.

The minister was speaking at a meeting with reporters at the Saudi embassy in Washington.

"We have presented a list of demands to Qatar, made our point, explained our position and taken our decision. This list of demands is non-negotiable and should be implemented in full," remarked Al Jubeir.

The Saudi-led coalition has laid down a list of 13 demands for Qatar, included the closure of Al Jazeera TV network, a downgrade of diplomatic ties with Iran and the shutdown of a Turkish military base in the emirate.

"The measures taken towards Qatar in its capacity as a neighbouring sisterly country are painful to us, but its non-abidance with Riyadh Arrangement, its support for extremist and terrorist groups as well as its provocation and interfering in the domestic affairs of a number of countries, is unacceptable, not only for the boycotting countries but for all countries of the world hoping that wisdom will prevail and be observed by our brothers in Qatar and they stop such support and interference," he added.

Meanwhile, Qatar said that its Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani will be addressing the media tomorrow (June 29) at the JW Marriott Washington DC on this issue.

The minister will explore the challenges and prospects for resolving the Gulf crisis, and comment on the list of demands presented by the Saudi-led coalition, it added.
