A man has been arrested in France for deliberately driving his car into groups of pedestrians, while shouting Allahu Akbar - an Islamic phrase meaning God is great.

Two people are seriously hurt and nine others have minor injuries. It happened in the city of Dijon.

This latest attacker was known to authorities, a source close to the investigation said.

"The man, born in 1974, is apparently imbalanced and had been in a psychiatric hospital," the source said, adding that "for now his motives are still unclear".

According to French newspaper Le Figaro, three people were in the car at the time of the attack.

It came a day after French police shot dead another man who stabbed three officers in a police station in the central town of Joue-les-Tours.
