Saudi official refuted the claims of Qatari officials over the Saudi position from the Iraqi invasion of Kuwait, saying that his country expressed its support for Kuwait since the beginning of the crisis. Saudi Adviser of Saudi royal court Saud Al Kahtani said that the Qataris realize that former President Saddam Hussein offered to former King to share the Gulf Cooperation Council, while the Saudi response was on the ground.

He added that the Qatari government insisted to host the Gulf Summit to discuss the invasion of Kuwait, saying that the emir’s son Hamad Bin Khalifa said that they will not discuss the issue if the summit did not take decision to end the conflict over Hewar Island, while King Fahd rebuked him for his bad morals.

On the political side, French Foreign Minister Jean-Yves Le Drian called Sunday for a “de-escalation” in the row between Qatar and the four Arab countries, as he held talks in the UAE and Kuwait, acting as mediator in the crisis. “It would be preferable if the parties could engage in a process of de-escalation, one that is indispensable so that negotiations can take place in a constructive atmosphere,” Le Drian said in Abu Dhabi.

He held talks with Shaikh Mohammad Bin Zayed Al Nahayn, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces. Abu Dhabi was the last step in a tour of four Gulf nations that began Saturday and also took Le Drian to Qatar, Saudi Arabia and Kuwait. Earlier Sunday, the French foreign minister held talks in Kuwait City with senior officials in a bid to bolster the emirate’s attempts to mediate in the Gulf crisis.

Le Drian met with the emir, Shaikh Sabah Al Ahmad Al Sabah, and Kuwait’s foreign minister, state news agency KUNA said, for talks on a regional rift which has seen Saudi Arabia, the UAE, Egypt and Bahrain sever all ties with Qatar.

The French foreign minister has supported Kuwait as a mediator in the crisis, which he said should be resolved “by the Gulf countries themselves”. “France does not want to substitute the mediator,” Le Drian said in Saudi Arabia on Saturday. “It wants to be a facilitator by joining efforts of other countries.”

Le Drian’s visit comes after a four-day mediation mission by US Secretary of State Rex Tillerson ended on Thursday with no announcement of progress towards defusing mounting tensions in the Gulf. Saudi Arabia and its allies imposed sanctions on Doha on June 5, including closing its only land border, denying Qatar access to their airspace and ordering their citizens back from the emirate. The four Arab states want Qatar to sever ties with Iran and stop funding Islamist extremist groups.
