The threat of a terrorist attack in France is at its highest level following a foiled car-bomb plot by three radicalized Islamist women, French Prime Minister Manuel Valls told Europe1 radio on Sunday.
In France, there were currently 1,350 people under arrest and being investigated for terrorism, while 293 were suspected of being in direct contact with a terrorist organization, Valls said.
Police arrested three women on Thursday, accused of planning to blow up a car filled with gas canisters near Notre Dame Cathedral in the centre on the city.
One of the women was charged on Saturday.
Some 15,000 radicalized people were under investigation, Valls said.
