Labour leadership frontrunner Jeremy Corbyn has questioned the point of the military action that killed Islamic State (IS) terrorist Reyaad Khan in Syria.

The left-winger said he would not have authorised the drone attack that killed the British jihadi and insisted David Cameron "has some very difficult questions to answer about the legality of what he did".

Khan was killed in an unprecedented targeted air strike that also killed Briton Ruhul Amin on August 21 in the IS stronghold of Raqqah.

The Herald:

The Prime Minister said the attack was justified on the grounds of "self-defence" because Khan was involved in orchestrating a number of plots to attack "high-profile public commemorations" over the summer.

Defence Secretary Michael Fallon has insisted the Government would not hesitate to take similar action against others on a reported "hit list" Is extremists.

But Mr Corbyn, chairman of the Stop the War Coalition, questioned the legal basis for the use of drones when details of the operation emerged and has now suggested there was no point in targeting the jihadi.

He told ITV News: "I'm unclear as to the point of killing the individual by this drone attack."

The potential election of Mr Corbyn as Opposition leader could make it harder for the Government to obtain parliamentary approval for military action in Syria - though ministers have hinted they could still attract sufficient Labour support.
