The world’s leading terrorist network has received millions of dollars from Saudi Arabia, which is also the largest source of cash for terror groups around the world, according to a report released on Thursday by the U.N. Human Rights Council.

The report details the role of the Saudi-led coalition fighting ISIS and the Saudi regime’s support for terror, including funding for extremist groups and weapons.

“ISIS and its affiliates are financing and deploying in Syria, Iraq and Libya, using the Saudi government as a front,” said Nadim Houry, the U the report’s author and a U.S. citizen.

“These funds, which the U, Saudi Arabia and the Gulf States continue to provide, have enabled ISIS and its affiliated forces to carry out horrific atrocities in Iraq, Syria, Yemen and elsewhere.

ISIS is using Saudi Arabia as a weapon, not only in Iraq and Syria, but also in Lebanon, Somalia and Yemen.

ISIS continues to use Saudi Arabia to support terrorist attacks in the region and beyond.”

The report states that ISIS “has not stopped funding and arming extremist groups, particularly ISIS,” but instead “has expanded its operations in the Gulf, particularly through the expansion of its activities in Libya.”

It also notes that Saudi Arabia “continues to support terrorism and other extremist groups around its borders.”

The findings come amid a surge in ISIS attacks in Europe, which has seen a rise in the number of suicide bombings, including one at a train station in the German city of Dortmund, which killed eight people.

In recent weeks, a number of attacks have been claimed by ISIS in France, Belgium, Germany and the United Kingdom.

The United States has repeatedly warned of a “dangerous, new threat” from ISIS in Europe.

The group has claimed responsibility for a number attacks in France and Belgium that killed more than 60 people, including an attack on a church in the French city of Villejuif, that left at least 12 people dead and more than 150 wounded.

In Germany, the Federal Criminal Police Office has been criticized for not pursuing the alleged perpetrators of a series of attacks that killed four people and wounded dozens more in Munich, which have since been linked to ISIS.

The government of Bavaria has also come under fire for its handling of the migrant crisis.

Last week, Chancellor Angela Merkel announced that Bavaria will become the first state in Germany to accept Syrian refugees, an announcement that came just days after ISIS claimed responsibility in a video for a deadly attack in Munich.

In the wake of the Munich attack, the government of neighboring Austria announced it was taking a similar approach to its border with Hungary, where the Islamic State has established a base.

In June, Austria imposed a temporary ban on entry to Syrian refugees from Turkey and a series in France following attacks in that country, but it is expected to ease the restrictions in the coming weeks.

The U.K. is also facing a growing threat from the Islamic Group, with reports that ISIS has been training young Britons to carry weapons, and British police have been accused of using excessive force to break up protests.

ISIS has also reportedly been able to smuggle weapons into the country.
