Russian officials are planning to put a forward operating base in Syria according to U.S. officials.

Pentagon spokesman Jeff Davis told a group of reporters that the steady flow of equipment and personnel into the region is leading intelligence officers to that conclusion.  The Russian government has also been sending in heavy equipment and weapons into the base via cargo flights.

“We have seen indications in recent days that Russia has moved people and things into the area around Latakia and the air base there that suggests that it intends to establish some sort of a forward air operating base,” Davis said.

At least two flights a day have been taking place according to Davis.

Russia is a key ally of Syrian President Bashir al-Assad and has stopped many actions in the United Nations against Assad through the use of their permanent veto in the U.N. Security Council.

State Department spokesman John Kirby said that the U.S. does not understand Russia’s ultimate goal in Syria.

“Clearly, they are providing more assistance,” Kirby said. “But the ultimate goal? The ultimate intent here? I think there’s still a degree of opaqueness about that.”
