The Conservative MP Mark Pritchard has said that new laws should be brought in requiring the families of people who travel abroad to take part in jihad to contact police.
"I think we need to look at every measure that would increase our national security", he told Good Morning Britain.
He added that it was "incumbent" on family members to report those who had gone abroad to fight in the interest of protecting their own local communities and the national interest.
