kerry USUS Secretary of State, John Kerry, held talks with Saudi Arabia’s deputy crown prince, Mohammed bin Salman, early this morning on ways to end Yemen’s conflict and resume peace talks between the warring sides.

Kerry arrived in Jeddah from Nigeria for discussions with Saudi leaders and other Gulf Arab states and will also update them on US meetings with Russia addressing military cooperation in Syria.

The talks come as Syrian rebels backed by Turkish special forces, tanks and warplanes entered one of Islamic State’s last strongholds on the Turkish-Syrian border. It is Turkey’s first major US-backed incursion into its southern neighbor.
