Amid intense fighting in Syria, with more reports of barrel bombs being used, rifts within rebel ranks are becoming increasingly deadly.
Britain has accused the Assad regime of committing what it called “yet another war crime” by spraying civilian areas with the weapons – oil drums or cylinders packed with explosives and metal fragments and dropped from aircraft.
Rival rebels meanwhile are battling
for supremacy, with increasingly bloody consequences.
Seen as Syria’s most hardline rebel group, the ‘Islamic State in Iraq and the Levant’ is said to have killed hundreds of fellow anti-Assad fighters in recent days.
Some reports say civilians have also been killed by the al Qaeda-linked militants as they battle to keep territory won out of rival rebel hands.
