U.S. Secretary of State John Kerry has arrived in Saudi Arabia, where he is expected to present proposals on ending Yemen's 16-month conflict that has killed more than 6,500 people, about half them civilians.
Saudi Arabia leads an Arab coalition that began air raids in March 2015 and later sent in ground forces to support Yemen's internationally recognized government after Huthi Shiite rebels and their allies overran much of the country.
With the civilian death toll climbing, the kingdom has faced mounting criticism from human rights groups.
As Kerry landed in Jeddah late on August 24, a U.S. official said the secretary of state would also update Saudi leaders on U.S. meetings with Russia addressing military cooperation in Syria.
Kerry arrived from Nigeria and Kenya on a trip focused on counterterrorism.
