GCC leaders discuss Yemen crisis at summit in Riyadh

The leaders of Gulf Arab states arrived in Saudi Arabia on Tuesday for their annual summit, a united meeting that comes amid heightened tensions over Iran’s nuclear program and after a yearslong boycott of Qatar.

The Gulf Cooperation Council Summit, previously a contentious affair given that three out of the six members cut ties with Qatar in 2017, follows a rare regional tour by the Saudi crown prince to rally support among neighboring allies.

At the summit nearly a year ago Saudi Arabia spearheaded an end to the four-nation embargo of Qatar, restoring diplomatic ties after years of hostility.

The UAE, Egypt and Bahrain have since followed suit in taking steps to reopen borders and mend ties with Doha.

The leaders convened as talks to revive Tehran’s tattered 2015 nuclear deal with world powers have floundered in Vienna.

Participants also discussed the ongoing war in Yemen which has seen involvement from both the UAE and Saudi Arabia, and has sparked one of the world's worst humanitarian crises.
