Since Libyan renegade military commander Khalifa Haftar began his offensive to take the capital Tripoli, he has courted the West by saying he is trying to rid the country of, in his words, "terrorists".

But elements within Haftar's forces have been accused of sharing an ideology similar to the al-Qaeda and the ISIL (ISIS) group.

And the Madkhalis fighters have also been accused of war crimes.
