Three women arrested after gas canisters found near Notre Dame in Paris

Three women have been detained in an anti-terror operation south of Paris in which one police officer sustained minor injuries by one of the women, who was also injured, the French interior minister said.

Bernard Cazeneuve said the detentions of the "radicalised" women aged 19, 23 and 39 in Essonne were linked to an investigation stemming from the discovery of a car parked near Paris' Notre Dame Cathedral with six gas canisters inside.

Paris prosecutors previously said that four other people were detained and they were suspected of being "radical Islamists".

Officials said that a 27-year-old man and a 26-year-old woman were detained south of Paris on Wednesday, and that a second couple, a 34-year-old man and a 29-year-old woman, were detained in the same case on Tuesday.
