Britain will introduce new laws this week to prevent airlines from carrying passengers who may be travelling to join Islamic State militants in Syria and Iraq.
Under the proposed new laws, Home Secretary Theresa May would be able to prevent airlines from carrying passengers, including children, believed to be travelling to take part in "terrorism-related activity" on known routes, such as those into Syria, according to a Home Office statement.
"This important legislation will disrupt the ability of people to travel abroad to fight and then return," James Brokenshire, a junior minister for security in May's department, said in the statement. It will also enhance our ability to monitor and control the actions of those who pose a threat," he added.
The rules would require airlines to seek permission to carry such passengers. An automatic system based on passenger lists provided by airlines would flag high-risk travellers and stop them boarding aircraft.
