The Islamic State of Iraq and Syria has threatened to invade Jerusalem and wave its flag in Islam's holy places even if the West and the Jews object. ISIS militants claim they will expand the caliphate and rule in Saudi Arabia, Jerusalem and Rome.

The group's planned expansion of its caliphate appears in the foreword of the fifth edition of ISIS' official publication, Dabiq, named after a town in Syria's Aleppo. Previous reports have revealed ISIS militants believe a great war between the West and the Muslims will take place after ISIS forces have seized control of Syria.

As written in Dabiq, ISIS plans to spread its rule in the Arabian Peninsula, Libya, Yemen, Algeria and the Sinai Peninsula. The extremist group has promised to raise the ISIS black flag in Jerusalem including Saudi Arabia's Mecca and Medina.

The organisation reveals in the magazine that ISIS will be targeting the East and the West to prepare for an expansion "by Allah's permission" and "put an end to the Jewish State" including the "allies of the cross." ISIS said it wants to fill the world with the "truth and justice of Islam" even if the United States and its allies do not agree, Jerusalem Post noted.

Meanwhile, a radical Muslim preacher in Jerusalem has praised ISIS for its plans of fighting the Jews and Americans. Ali Abu Ahmad held an impromptu sermon in the Al-Aqsa mosque in Jerusalem and called for a caliphate similar to what ISIS is attempting to achieve in Iraq and Syria, according to Breitbart. The preacher urged the people in the mosque to desire for a caliphate that will protect, defend free Jerusalem from the Jews, whom he described as "the most vile of creatures."

He called on the people to not turn to the international community or the UN Security Council since he claimed they brought the Jews to Palestine lands. Ahmad blamed the West for barbaric crimes against the Muslims in Palestine.

Due to fears of rioting, Israel has restricted the number of Muslim worshippers visiting mosque in the past several months. Israeli authorities relaxed measures after the U.S. and Jordanian officials urged Israel to do so to curb anger and violence.
