France frets over internal threat two years after attacks in Paris

PARIS - Two years after militants killed 130 people in coordinated attacks across Paris, French officials said there remains an unprecedented level of "internal" threat from both within and outside the country.

With the Islamic State group losing ground in Iraq and Syria, hundreds of French citizens - and in some cases their children - have started to return to France, leaving the government in a quandary over how to deal with them.

For the first time as president, Emmanuel Macron was scheduled to pay tribute on Monday to the victims of the mass shootings and suicide bombing that took place across Paris and in the city's northern suburb of Saint-Denis on Nov 13, 2015.
