The minute-long footage shows two Spanish-speaking men saying Spain is the land of their forefathers and that they are prepared to die for their nascent Islamic State.
The men said the ISIL would not stop at Spain and intends to spread its Islamic Caliphate across the world.
“I say to the entire world as a warning: We are living under the Islamic banner, the Islamic Caliphate. We are going to die for it until we liberate all the occupied lands, from Jakarta to Andalusia,” one of the men said.
In an audio recording distributed on extremist websites on June 29, the ISIL militants claimed the formation of a so-called Islamic caliphate or state, declaring the terrorist group’s leader Abu Bakr al-Baghdadi as “the caliph” and “leader of Muslims everywhere”.
The crisis in Iraq escalated after the ISIL militants took control of Mosul, in a lightning advance on June 10, which was followed by the fall of Tikrit, located 140 kilometers (87 miles) northwest of the Iraqi capital Baghdad.
An estimated 1.2 million people have been displaced in Iraq so far this year, according to the United Nations.
The ISIL has vowed to continue its raid towards Baghdad.
Soldiers of the Iraqi army have been engaged in heavy fighting with the militants on different fronts and have so far been able to push back militants in several areas.
