Experts warn that ISIS attacks are happening every 84 hours spreading more dread and panic across the western world.

Intelligence group IntelCenter, which studies terrorist activities, has revealed that terror assaults linked to, or inspired by, the death cult are happening every three to four days since June 8.

This data does not include mass killings in war zones in Iraq, Syria, Sinai in Egypt and Libya.

IntelCenter warns that half of the attacks have taken place outside major cities in Europe and in other western democracies worldwide.

The expert group warns that many of the targets are those "not traditionally under threat of terrorist attacks.”

On June 12, ISIS fanatic Omar Mateen slaughtered 49 people at the Pulse nightclub in Orlando, Florida,

The mass shooting was one of the worst in the modern history of the Unites States.

Since June, France and Germany have both been plagued with terror attacks, the worst of which occurred in Nice on July 14.

During the Bastille Day celebrations in the southern French city, a crazed killer Mohamed Lahouaiej-Bouhlel drove a 19 tonne truck into a crowd of people watching a fireworks display.

The brainwashed fanatic murdered 84 people and injured another 308 innocent people.

On July 24, an ISIS suicide bomber blew himself up outside a bar in Ansbach, Germany, when his plot to attack a music festival was foiled.

Bomber Mohammad Daleel, a 27-year-old Syrian refugee, had pledged allegiance to Abu Bakr al-Baghdadi, leader of the Islamic State.

The crazed attacker was the only fatality in the incident.

Two days later, a pair of homegrown Islamic extremists stormed a Catholic Mass in the quiet French town of Saint-Etienne-du-Rouvray, Normandy.

Teenagers Adel Kermiche and Abdel Malik Petitjean, who had both previously tried to flee to Syria to join the depraved terror group, murdered an elderly Catholic priest and severely wounded another man before being gunned down by police.
