Obama has stressed that the U.S. would continue to support the Syrian opposition as Russia enters the war-torn country

The latest U.S. assessment of Moscow's activity in Syria is that Russia has moved in several ground combat weapons and troops

Washington CNN —  

President Barack Obama authorized the resupply of Syrian Kurds and the Arab-Syrian opposition as part of a strategy to put pressure on ISIS from the north and strengthen the border, according to two senior administration officials.

The approval came at a National Security Council meeting on Thursday.

CNN reported over the weekend that Obama emphasized to his team that the United States would continue to support the Syrian opposition as Russia enters the war-torn country.

“President Obama was clear that we intend to continue our efforts to degrade and ultimately destroy ISIL in Syria and to keep supporting the moderate Syrian opposition,” an official said.

While Russia has said that it is conducting military operations to wipe out ISIS, U.S. officials have questioned that aim given that many of its airstrikes have not targeted places ISIS is active. Instead, they have seen the effort mostly as a move to bolster close Moscow ally President Bashar al-Assad.

The latest U.S. assessment of Moscow’s activity in western Syria indicates Russia has moved several ground combat weapons and troops into the area to potentially back up Syrian forces in the field planning to attack anti-regime forces, according to two U.S. defense officials.

The U.S. views the move as Russia “stepping up its ground activity” in Syria to attack those forces, rather than ISIS elements, according to one of the officials.

It’s believed the Russians are positioning weapons to support a Syrian ground offensive, officials said.

The equipment includes artillery as well as four BM-30 multiple-launch rocket systems – all considered to be highly accurate. The latter is capable of rapid-fire rocket launches.

Several weeks ago, Russia moved about half a dozen artillery pieces into Latakia port.

The United States originally thought the move might be for defense of the port, but the latest action is an indication of potential ground attacks in the coming days, an official said.

The weapons have been spotted between Homs and Idlib and west of Idlib.

It is not clear if they’re now in final position for possible artillery strikes.

The officials also said Russia has moved electronic jamming equipment into Syria. Both a truck-mounted system and a number of pods that can go on aircraft have been observed. The equipment could potentially give the Russians the ability to jam electronics of U.S-backed coalition aircraft.
