A delegation of U.S. senators led by John McCain has met with Saudi Arabia's crown prince in the kingdom, where talks focused on the training of Syrian rebels.

A message on the official Twitter feed for McCain, a Republican from Arizona, said that the U.S. delegation also met Saturday with the head of the Western-backed Syrian National Coalition, Ahmed al-Jarba, and the commander of Saudi Arabia's training and equipment program. They also met in Qatar with the country's emir.

Saudi Arabia is part of a U.S.-led coalition conducting airstrikes in Syria against the Islamic State group.

On Friday, the Pentagon said that as many as 1,000 U.S. troops and trainers would be sent to training sites in Turkey, Saudi Arabia and Qatar to help arm and train select Syrian rebels.
