Syrian rebels on the attack, according to unverified footage.<br/> <br />This video from a social media website, purports to show rebels battling to capture a key government air base near Aleppo on Wednesday.<br/> <br />A monitoring group said the attack at Taftanaz was indeed underway.<br/> <br />The Syrian Observatory for Human Rights claimed the rebels forces were made up fighters from the al Qaeda-linked al-Nursa Front and the Ahrar al-Sham Brigade, rmaking another attempt to capture the base.<br/> <br />The future of the conflict may turn on air power.<br/> <br />The lightly armed rebels have made gains over recent months but have faced increasing use by President Bashar al-Assad's forces of attack jets and helicopters - this is unconfirmed activist footage of government jets in action over Damascus last week.<br/> <br />No surprise the rebels have turned their attention to air bases.<br/> <br />There was no mention of the Taftanaz battle on Syrian government controlled media -- and restrictions on independent journalists make reports hard to verify.<br/> <br />The attack comes against the gloomy backdrop of the latest estimate in numbers of dead.<br/> <br />The United Nations now says more 60,000 people have died since Syria's uprising began almost two years ago.
