France struck ISIS bases overnight: Defence minister

France's defence minister said on Monday that French air forces conducted further strikes overnight on Islamic State (ISIS) targets.

Speaking after national defence council meeting in the wake of the recent truck attack on the city of Nice, Jean-Yves Le Drian told reporters the fight against Islamist militants bases was continuing.

Interior Minister Bernard Cazeneuve, addressing reporters alongside Le Drian, said internal security was being boosted with a call-up of reservists in France that would put about 3,000 additional police on patrol over the summer period, at beaches and summer festival sites in particular.

There was however "no zero risk", he said, stressing that France had never before faced a terrorist threat of such a high level.
