ots streaking across the sky, the battle for Syria's ancient city of Palmyra rages on. This footage showing what is said to be Islamic State fighters firing relentlessly across a field, shouting, God is great.>>
Control of Palmyra has been going back and forth between the militants, and Syria's Russian backed army.
Both sides have claimed the upper hand. Russia said its jets had helped force the militants out of the city center overnight, but a news agency linked to Islamic State, said it had only briefly retreated and was now back in. Palmyra is the site of spectacular ruins in the center of Syria.
It was recaptured from Islamic State in March, but the militants group made a surprise advance on the city last week, forcing the Syrian army to divert its troops from Aleppo. Now, it's yet again a battleground.
