The UK is going to seize the passports of any citizen who joined jihadists in the Middle East to prevent them from returning home.

Prime Minister David Cameron outlined the government’s new regulations to seize regulations that would include landing bans on airlines that fail to comply with no-fly lists.

UK intelligence officials say that at least 500 radicalized Britons are fighting in Iraq and Syria.

“We will shortly be introducing our own new Counter-Terrorism Bill in the UK,” Cameron said.  “New powers for police at ports to seize passports, to stop suspects traveling and to stop British nationals returning to the UK unless they do so on our terms.  New rules to prevent airlines that don’t comply with our no-fly lists or security screening measures from landing in the UK.”

Leaks to British media say the new rules could include admission back into the country if they agree to face charges related to their jihadist actions or de-radicalization courses.

“The root cause of the challenge we face is the extremist narrative. So we must confront this extremism in all its forms,” Cameron said.  “We must ban extremist preachers from our countries. We must root out extremism from our schools, universities and prisons.”
