Saudi F-16 aircraft reportedly arrive at Turkish air base to join fight against IS

Turkish Defense Minister Ismet Yilmaz denied a report that some Turkish soldiers had entered Syria over the weekend and said Ankara was not considering sending troops into its neighbor, the state-run Anadolu Agency reported on Monday.

Syria's government had said Turkish forces were believed to be among 100 gunmen who entered Syria on Saturday with 12 pickup trucks with heavy machine guns mounted, in an operation to supply insurgents fighting Damascus.
