Members of the Free Syrian Army initiate a full-scale assault against an Iranian backed Hezbollah compound inside of the city of Busra al-Sham in 2014.

What you're looking at here is an assault that's kicked off with an improvised explosive device utilized as a breaching charge. While we don't directly see the cameraman make entry into the compound, the rate of fire at the onset of this attack implies that the intent was indeed to breach into the compound and clear it of Hezbollah fighters entirely. This attack took place in the Syrian city of Busra, better known in Syria as Busra al-Sham in 2014 before the Free Syrian Army was entirely radicalized by the extremist factions who started joining forces with them later in that same year.
