A woman (centre, wearing a hood) being taken out of a building in Boussy-Saint-Antoine, south of Paris, where female suspects - said to have been planning new acts of violence - were arrested. French police investigating Sunday's discovery of a car with gas cylinders near Notre Dame Cathedral in Paris arrested the three women on Thursday. French President Francois Hollande said yesterday a terror attack was "foiled" after the arrests of Ines Madani, 19, and the two others. But he warned that other terror groups were still "out there". Investigators believe Madani is the main suspect in the probe into the car laden with gas cylinders. She reportedly stabbed a police officer during her arrest, before being shot and wounded.
