British Prime Minister David Cameron announced Monday that terror suspects will be forced to enter de-radicalization programs and relocate, with police being designated with temporary enhanced powers to keep Islamist extremists in Britain from traveling to Syria and Iraq, the Telegraph reported. The latest move comes as part of a package of tough new measures to combat the threat of returning British jihadists.

If suspected extremists are caught, they will be ordered to participate in programs to combat their fanatical views, the Prime Minister said. They may also be forced to leave their home town or city and move away from associates under revived powers to relocate terror suspects.

The announcement came days after Britain raised its terror threat level from "substantial" to "severe," and follows the death of American journalist James Foley at the hands of an ISIS fighter who appeared to have a British accent, NBC News reported, adding that 500 people are believed to have traveled from Britain to fight with extremists groups.

"The ability to relocate suspects to other areas was abandoned when control orders were replaced by the weaker terrorism prevention and investigation measures (Tpims) following a series of court rulings," according to the Telegraph. "The loss of the power has been partly blamed for at least one recent absconding by a Tpim suspect who disappeared after being able to return to London. " But Cameron has now signaled moves to restore the controversial power.

In addition, Cameron told parliament that police would have the ability to temporarily seize the passports of suspected militants en route to Syria or Iraq.

"Adhering to British values is not an option or a choice," Cameron told the Commons. "It is a duty for all those who live in these islands so we will stand up for our values, we will in the end defeat this extremism and we will secure our way of life for generations to come."

"We have all been shocked and sickened by the barbarism we have witnessed in Iraq this summer, the widespread slaughter of Muslims by fellow Muslims, the vicious persecution of religious minorities such as Christians and Yazidis, the enslavement and raping of women and, of course, the beheading of American journalist James Foley with the voice of what seems to have been a British terrorist recorded on that video," he said.

"The European Council conclusions could not be clearer, and I quote, the European Council believes the creation of an Islamic Caliphate in Iraq and Syria and the Islamist extremism and export of terrorism on which it is based is a direct threat to every European country."

In the meantime, Britain and other world powers need to help Syria and Iraq form "free and open societies" because "we know that terrorist organizations thrive where there is political instability," Cameron stated.
