Saudi Arabian foreign minister Adel Al-Jubeir sent a stern warning to Qatar, only a day after the Saudi ambassador to the UN appeared to reduce the demands from 13 to 6.

Speaking after a meeting with his Belgian counterpart in Brussels, Adel Al-Jubeir said:

“We came to the conclusion that enough is enough. If Qatar wants to be part of the Gulf, it has to act like it. And stop engaging with this mischief. If not, we are prepared to wait for long time. We are not in a hurry. But we can not go back to the way they were”.

He added that: “the Qataris know exactly whats required from them, they have to respond to it. Thats where we are”.

This weekend the EU’s foreign policy chief Federica Mogherini will travel to Kuwait, in an attempt to reach a diplomatic solution to the crisis. It is a move that Abu Dhabi-based analyst Richard Burchill says Gulf states will welcome.

Burchill told euronews: “Europe has a lot of experience in dealing with opposing views and bringing people together to address issues of common concern. Europe also has extensive expertise and institutional capacity in dealing with funding of terrorism and support for extremism. So the presence of the EU is to be welcomed, because right now we can not rely on a coherent US position. So Europe can bring some leadership, can bring some objective balance to the debate and discussion. And we will certainly welcome their greater involvement. “

The current crisis began in June, as Saudi Arabia and allies such as Egypt withdrew ambassadors and imposed trade bans over allegations of Qatari support for terrorism.

Qatar has not yet responded to the demands.
