Last week ISIS released another propaganda image featuring bullet-ridden photos of President Donald Trump and Russian President Vladimir Putin, inviting its followers to stage more attacks on the group's two leading foes abroad.
The image, shared throughout pro-ISIS channels on the encrypted messaging application Telegram, featured an excerpt of a Quranic verse manipulated by the ISIS followers to urge fellow jihadis to take every opportunity to conduct deadly attacks in the U.S. and Russia.
Despite the jihadis suffering severe territorial losses to military campaigns sponsored by Moscow and Washington, the image also claimed that ISIS would overcome its enemies on the battlefield.

"Putin cut his teeth destroying the Chechens.
"He regarded their rebellion as a manifestation of Islamic extremism.
"He also bolstered his own personal popularity in Russia by demonising the Chechens as Islamic terrorists and by brutally crushing them."
