Four people were killed and 12 more injured by a gunman who opened fire at a busy Christmas market in Strasbourg, eastern France, on Tuesday, the city's mayor told AFP.
Three or four of the injured are in critical condition, Mayor Roland Ries said.
A manhunt was underway after the assailant managed to flee after exchanging shots with security forces patrolling the area at around 8:00 pm (1900 GMT).
