Dubai: Kuwait's emir left Saudi Arabia after what state news agency KUNA described as a "brotherly visit" but there was no word on the outcome of the talks with King Salman Bin Abdul Aziz on a major diplomatic rift.

State news agency KUNA said Emir Shaikh Sabah Al Ahmad Al Jaber Al Sabah left Jeddah along with senior officials who accompanied him. It was not immediately clear if he was flying straight home or making any stops on his way back to Kuwait.

The Saudi state news agency had earlier reported that King Salman and Shaikh Sabah had discussed the "development of events in the region," but gave no details.

Saudi Arabia, the UAE, Bahrain and Egypt  all announced they would withdraw their diplomatic staff from Qatar, while Saudi Arabia also said Qatari troops would be pulled from the ongoing war in Yemen.

Saudi Arabia said it took the decision to cut diplomatic ties due to Qatar's "embrace of various terrorist and sectarian groups aimed at destabilizing the region" including the Muslim Brotherhood, Al Qaida, Daesh and groups supported by Iran.

In its latest measure, Saudi Arabia revoked the licence of Qatar Airways, telling the airline to close down all offices.

“The General Authority of Civil Aviation has decided to cancel all licences granted to Qatar Airways and to close all of its offices in the kingdom within 48 hours,” a statement carried by the official SPA news agency said.

Qatar must 'change policies': Saudi foreign minister

In Paris, the Saudi foreign minister said on Tuesday that Qatar must "change their policies" and stop supporting "extremist groups".

"They have to change their policies" and "stop supporting extremist groups," Adel Al Jubair told reporters, adding that Qatar needed "to act like a normal country."

The minister did not specify what he wanted from Qatar, saying that "a number of steps can be taken, they know it".

When asked about possible diplomatic efforts to end the crisis, he said, "I don't believe there is a mediation. This is an internal GCC (Gulf Cooperation Council) issue."

"We decided to make it clear that enough is enough," Jubeir said. "We want Qatar to be an ally in finding peace and stability in the region."
