Hollande leads tributes to 2015 terror attack victims in Paris

French President Francois Hollande led a commemoration as thousands gathered in Paris to pay tributes to the victims of the terrorist attacks in the country in 2015.

According to The Guardian, Hollande and the mayor of Paris, Anne Hidalgo, unveiled a plaque and a memorial oak tree in Paris's Place de la Republique in memory of those killed in a series of attacks that shook France.

Seventeen people were killed in the Charlie Hebdo and kosher supermarket massacres in January, and a further 130 died in the November carnage on bars, a rock concert and the national stadium.

At the low-key ceremony, veteran French rocker Johnny Hallyday performed a song in memory of 2015's vast street marches to mark the Charlie Hebdo attacks.
