MOSCOW (Sputnik) — The press release of the UK government said:
"Parents concerned that their 16 and 17 year old children are at risk of traveling abroad under the influence of extremists will be able to apply to have their passports removed."
Cameron is also expected to announce as a part of UK nationwide measures to counter terrorism that those involved in extremist activity will be automatically restricted from working with vulnerable people and children.
The number of UK citizens under 20 who have been involved in counter-terrorism related arrests is rising, the release said, citing recent British police figures.
According to the latest data from the UK Metropolitan Police, at least 700 UK citizens are estimated to have left for Syria and Iraq to fight alongside jihadists.
