British Prime Minister David Cameron has outlined plans to seize passports from British nationals linked to armed groups and stop them returning from fighting overseas.
Cameron has also proposed landing bans on airlines that fail to comply with London’s no-fly lists.
“We will shortly be introducing our own new Counter-Terrorism Bill in the UK,” Cameron said in a speech to Australia’s parliament before travelling to the G20 leaders’ summit in Brisbane, adding that there was “no opt-out from dealing with this”.
“New powers for police at ports to seize passports, to stop suspects travelling 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.”
Some 500 radicalised Britons are estimated to be fighting in Iraq and Syria, both of which are facing a major offensive from the Islamic State of Iraq and the Levant (ISIL).
