Islamic State (IS, formerly ISIS/ISIL) forces attacked a known special forces base in Syria, but the British government has refused to confirm its soldiers were there.
UK special forces are known to use the al-Tanf garrison as a base to train ‘moderate’ Syrian rebels. The US also has troops stationed at the base.
The UK presence became public knowledge after images were leaked to the press in 2016.
Reports by the Telegraph indicate an IS assault force composed of an estimated 30 suicide bombers and fighters attacked the base on Sunday.
