It's reported three women have been arrested after a car filled with gas canisters was left near Notre Dame Cathedral in Paris.

The discovery last Saturday night triggered a counter-terrorism inquiry.

French media are reporting that a police officer was injured during the arrests to the south east of the capital.

Two people - including the car's owner - have already been held by police.
