Syria's ever changing battle lines have become even more complex since Russian air strikes began two weeks ago.

The Kremlin says the air strikes have intensified this week. 

They appear to have provided the Syrian government an opportunity to start a new ground offensive.

Thousands of Iranian troops have reportedly been drafted in to fight alongside Syrian government and Hezbollah forces.

Syrian opposition fighters say they are ready for the fight after being re-supplied with US made anti-tank missiles to help turn the tide against the Syrian regime.

So, is the tug of war over Syria heating up between Russia and the US?

Will it lead to resolution or deeper conflict?
