The Egyptian wing of ISIS Takfiri terrorists has released a new execution video, declaring war on the Palestinian Hamas resistance movement based in Gaza.

The video, released Wednesday, purports to show the execution of a man who ISIS claims cooperated with Hamas’ armed wing.

“Never surrender to them. Use explosives, silenced pistols and sticky bombs. Bomb their courts and their security locations, for these are the pillars of tyranny that prop up its throne,” said one of the militants in the video.

The Egyptian wing of ISIS, known as the Sinai Province, is notorious for its brutal massacres, including the Sinai 2015 plane crash which killed 224 passengers and mass killing of over 300 people at a Sufi mosque in Egypt’s Sinai Peninsula, the deadliest attack in modern Egyptian history.

The video comes as Hamas has been cooperating with Egyptian security forces to restore stability to Sinai, which borders Gaza.

In October, the Palestinian resistance movement arrested four senior ISIS terrorists in Sinai.

In July 2015, ISIS released a video saying that it would overthrow Hamas “tyrants” for their perceived lack of religious rulings in Gaza.

Takfiri groups such as ISIS have never attacked Israel despite operating close to Syria’s borders with the occupied Palestinian territories. Israel is widely believed to be supporting terrorists in Syria by launching airstrikes against various targets there from time to time.

Meanwhile, the US and its allies, which have been conducting airstrikes against what are said to be ISIS targets inside Syria, have repeatedly been accused of providing logistic support and air cover for ISIS terrorists.

ISIS, however, lost all the territory under its control in Syria and Iraq late last year.
