Rebel forces launched their largest offensive against the Syrian government one week ago, capturing a significant area of land, including much of Aleppo city. According to BBC Verify, which tracks rebel advances through social media footage, the rebels have gained ground from north-west Syria.
The Syrian government and its key ally Russia responded with airstrikes in an attempt to counter the rebel gains. The situation remains volatile as the conflict continues to escalate.
