France remembers victims of Charlie Hebdo attacks
A ceremony has taken place in central Paris to remember those killed in the Charlie Hebdo attacks a year ago.
President Hollande laid a wreath in the Place de la Republique, where a commemorative oak tree was unveiled, and a minute's silence was observed.
In the attacks, jihadist gunmen killed 12 people at the satirical Charlie Hebdo magazine, four hostages at a Jewish supermarket and a policewoman.
