The Islamic State (ISIS) has produced a video threatening Hamas, Fatah and what it calls “the state of the Jews”.

The video was published Tuesday and targets “Hamas dictators” in Gaza. According to Reuters news agency, a masked individual warns, “We will uproot the state of the Jews (Israel) and you and Fatah, and all of the secularists are nothing and you will be over-run by our creeping multitudes.”

The ISIS member continues, “The rule of Sharia [Islamic law] will be implemented in Gaza, in spite of you. We swear that what is happening in the Levant today, and in particular the Yarmouk camp [in Syria], will happen in Gaza,” referring to the besieged Palestinian refugee camp near Damascus.

Tensions between Hamas and ISIS supporters in Gaza have been on the rise. Last month, an ISIS supporter was killed during an attempted arrest, leading to a spate of bombings against Hamas, as well as rocket fire on Israel aimed at drawing it into the conflict.

Despite this, Israeli Intelligence minister Yisrael Katz (Likud) told a security conference Tuesday, Hamas and ISIS were seen cooperating in the Sinai Peninsula, a claim Hamas vehemently denies.

“There is cooperation between them in the realm of weapons smuggling and terrorist attacks. The Egyptians know this, and the Saudis,” Katz said. “At the same time, within Gaza, ISIS has been flouting Hamas. But they have common cause against the Jews, in Israel or abroad.”

Although ISIS does not have an operational presence in Israel, it has many supporters in Gaza among those who feel Hamas is too “soft” on sharia law and on the Jewish state. Last week, the ISIS flag was seen flying on the Temple Mount and fliers signed “ISIS Palestine” were posted around Jerusalem.
