Police in Paris on Thursday shot dead a man attempting to enter a police station wielding a knife and shouting Allahu Akbar.
The man was carrying a mobile phone and sheet of paper with Islamic State flag and claim of responsibility, says Paris prosecutor.
According to police sources, the man was also wearing a fake suicide belt as he attempted to enter the police station in the 18th district at noon.
A huge security operation is underway in the north of the capital, with at least two local schools on lockdown.
The attack happened the same time on January 7, 2015 that two gunmen shot dead cartoonists and others at the satirical magazine’s offices.
France is marking the first anniversary of the Charlie Hebdo killings where a total of 17 people were gunned down by fanatics between January 7-9, 2015, including at a Jewish supermarket.

Earlier on Thursday, French President Francois Hollande visited the Paris police headquarters where he gave details of planned new security measures and paid tribute to the police, gendarmes and emergency services.
