ISLAMIC State claims to have blown 30 enemy aircraft out of the sky since April.
The terror group says it has shot down 30 planes, helicopters and drones in the past three and a half months.
It makes the outlandish boast in the latest edition of its propaganda newsletter Al-Naba – released this evening.
ISIS – also known as Daesh – claimed to have taken down a US warplane – killing all crew – in Iraq last week.
A slick infographic in Al-Naba – a digital magazine for jihadi fans – shows US and Russian aircraft going up in flames.
It claims to have shot down eight warplanes, four helicopters – including Apache choppers used by the US and Britain – and 18 drones.
The Pentagon denied claims the Islamist death cult shot down one of its planes near the Ain Al-Asad air base, which is about 100 miles from Iraqi capital Baghdad.
However, ISIS is known to have brought down a number of US drones.
Footage posted online shows jihadi fighters proudly showing off the wreckage.
But they are mainly unmanned spy aircraft – such as the AeroVironment RQ-20 Puma – rather than armed Predator or Reaper drones.Samsung Galaxy J7 – No Contract Phone – White – (Virgin Mobile)
