French president Francois Hollande said today that the "terrorist threat" continues to weigh on the country.
In a speech to police forces charged with protecting the country against new attacks, Mr Hollande said the government was passing new laws and ramping up security, but the threat remained high.
On January 7, 2015, a pair of extremist gunmen stormed the offices of satirical newspaper Charlie Hebdo, killing 11 people inside and a policeman outside.
Three police officers were among the 17 dead in the attacks last January, which ended after two days of bloodshed in the Paris region.
Mr Hollande said officers die in the line of duty "so that we can live free".
