This is the side that the UK Government is supporting in Syria, and who they want to replace Assad.
Your Government have given £millions of our taxpayers money to overfrow to fight the Syrian Government. Costly air attacks, dropping expensive bombs are trying to weaken the Syrian Government side, so that these Islamists can take over. And the US Government is supporting them too only more so.
Without our money and support, the fanatical Islamists would have been beaten years ago in Syria, so Evil *** like these would have been long dead years ago.
