Video footage of foreign jihadists in Iraq threatening to "conquer Jerusalem" has once again highlighted the dangers posed to Israel from Islamist extremists fighting in Syria's civil war.

At a public rally organized by the Islamic State of Iraq and the Levant (Syria), or ISIS, the speaker pledges his allegiance to the group's leader, Abu Bakr Al Baghdadi, and reiterates ISIS's long-term vision for the region.

"By Allah we will cleanse the Arabian Peninsula of you, you filth!" he declares, waving a sword, in a message to non-Muslims in the Middle East.

Focusing specifically on Israel, he vowed: "We shall conquer Jerusalem from you, oh Jews!"

A recent Arutz Sheva report noted that of all the factions opposing the rule of Syrian President Bashar al-Assad, ISIS is the "number one threat".

The clip was translated by MEMRI (the Middle East Media Research Institute.

Declaring his organization's ambitious aim to create a global Islamic state, the sword-wielding fanatic also looked further afield, promising to conquer Rome and "Andalusia", referring to parts of Spain which were once under Muslim occupation.

In a symbolic gesture he pulls out his passport - which reveals his Kosovan nationality - and throws it to the floor. His gesture was repeated by the other foreign fighters assembled around him, highlighting concerns over the steady flow of foreign jihadists - including western nationals - to the region.

ISIS, formerly known as the Islamic State of Iraq, is a radical group which broke away from Al Qaeda after a power struggle over its involvement in the Syrian civil war, as well as concerns that its brutal tactics were harming the global terrorist network's image in Syria.
