The sick ambitions of a caliphate bent on carnage: Chilling map predicts where ISIS will strike the West with 'lone wolf attacks' - as FBI sets up 56 centers to monitor Fourth of July terror threat

• e-mail

The FBI is setting up command centers at all of its 56 field offices across the country ahead of the July 4 weekend, to monitor any potential terrorist threats, law enforcement sources have revealed. 

Sources told Fox News that local, state and federal law enforcement agencies in the U.S. will be reporting any information about possible attacks to these command centers - where officials will decide how to respond.

The move comes amid growing fears that the terror group ISIS is working to awaken sleeper cells in Western nations, after sympathizers were linked to three back-to-back attacks in France, Kuwait and Tunisia last Friday.

While the FBI says there has been no specific credible threat so far, it seems to be more active in its warnings and actions ahead of Independence Day this year than previously.

This global map shows where ISIS has seized land, where it is expanding its support and where it has committed terror attacks. Most worryingly, it also reveals the countries where ISIS terrorists hope to carry out imminent attacks, including America. ISIS also wants to cause deadly disruption to Muslim regions of the world before the holy month of Ramadan ends on July 18

Another law enforcement source told Fox that the FBI has even been working to take known sympathizers for groups like ISIS off the streets of America before the symbolic holiday.

That could mean arresting these alleged sympathizers on U.S. soil on lesser charges and building a broader case while they are temporarily in custody over the holiday weekend.

The FBI is specifically concerned about targets like shopping malls - where there are large groups of people but relatively little security.

Rep Mike McCaul, chairman of the House Committee on Homeland Security has already warned Americans to 'remain vigilant' to terror attacks.

He also said that ISIS was no longer a regionalized threat but a global one.

‘I am extremely concerned that Syrian and ISIS recruiters can use the internet at lightning speeds to recruit followers in the United States, with thousands of followers in the United States, and then activate them to do whatever they want to do,’ he said, during an appearance on Fox News Sunday.

‘Whether it’s military installations, law enforcement or possibly a Fourth of July event parade.’

He added that America’s response had been slow in comparison to extremists’ rapid advancement of their internet presence.

Referring to the terror attacks in France, Tunisia and Kuwait last Friday, he said: ‘In light of the three attacks in three hours on three continents overseas, (it) shows us that ISIS is not just regionalized like the administration says, only in Iraq and Syria, but rather demonstrates a global threat - that they can conduct external operations and they’re very savvy doing that over the internet.'

A gunman opened fire on a beach packed with tourists in Tunisia, killing 38; a decapitated body was found after an attacker rammed his car into a gas container, triggering an explosion in France, and a suicide bomber attacker a Shiite mosque in Kuwait City, killed 27 and injuring 227. There is as yet no evidence that the attacks were coordinated. 

Meanwhile the FBI has issued a warning to local law enforcement officials across America about a heightened risk of terror attacks targeting Independence Day celebrations this weekend.

No specific threat has been made by the terror group but bulletins are frequently issued in advance of major U.S. holidays. 

The Institute for the Study of War, an influential think tank based in Washington DC, says that ISIS is soon likely to target other Western nations like the UK, France, Spain and Italy.

This week ISIS promised ‘paradise’ and ‘rewards in heaven’ for those who carry out attacks during the holy month for Muslims.

Terrorism experts say the threats should not be taken lightly.  

Federal investigators have disrupted a number of ISIS-inspired plots in recent weeks, including a planned assault earlier this month on police officers in Boston.

Authorities shot the alleged attacker, Usaamah Rahim, before he could attack officers with military-style knives.

An Islamic State suspect in New York was also arrested in a separate incident after he attacked an FBI agent with a kitchen knife during a search of his home.

Fareed Mumuni, 21, has now been charged with attempted murder and is accused of plotting to use pressure-cooker explosives and knives to kill police officers.
