France extends anti-terror border controls to April 2018

France will extend checks at borders with fellow Schengen members until April 30, the interior ministry said Thursday, citing the "persistent" terror threat to prolong controls in place since the November 2015 Paris attacks.

The controls at borders with members of the visa-free Schengen area such as Italy and Belgium, will "respect the principle of proportionality", the ministry said in a note to the EU dated October 3.

"Risk analysis... confirms the existence of a persistent level of threat," the ministry said, adding that it fears the Daesh terror group is planning further attacks on French soil.

Daesh claimed the coordinated series of attacks on Paris nightspots and the national sports stadium on November 13, 2015, which were planned from Brussels.
