The suspected gunman was 48 and known to law enforcement for non-payment of child maintenance, according to an official in the prosecutor's office in the nearby city of Clermont-Ferrand.

Officers from the local gendarme police service arrived at the house in the hamlet early in the morning, after receiving reports about a woman who had been beaten by her partner, the interior ministry said in a statement.

Officer Arno Mavel, 21, died from his injuries, the ministry said. In a second unit of reinforcements, Lieutenant Cyrille Morel, 45, and adjutant Remi Dupuis, 37, were both killed, it said.
