A year after the deadly Charlie Hebdo terrorist incident, Paris received a fresh scare of terrorism when a knife-wielding man who was trying to enter a police station was shot dead, CNN has reported.

The man had an image of the ISIS flag along with his body. He also carried a handwritten Arabic note that police officials say claimed responsibility of the deadly attacks that happened exactly a year ago. The office’s anti-terror section is investigating the case and Paris has been kept on high alert during the first anniversary of Charlie Hebdo.

The event took place at 11.30 AM, a year to the minute since the Hebdo killings. The man was heading directly towards a Police station in the Paris neighborhood of Barbes, holding a butcher’s knife while yelling “Allahu Akbar” repeatedly, the report said.

French Interior Minister Bernard Cazeneuve talked to the press and released an official statement saying that the French Police are trying really hard to figure out the identity of the man and his motivations. He was quoted in CNN as saying:

“In a country where the threat level is extremely high, the police and gendarmerie are on the front lines,” he said. “I’d like to thank them for their very great courage … and their commitment to protect the French people.”

According to News.com.au, the Commemorations will continue till Sunday when a 10m tall oak “remembrance tree” will be planted at the Place de la Republique, the square that saw thousands rally for support and unity to the Hebdo attack. The same place, that was also the center of anger and grief, when 130 people were killed over the co-ordinated terrorist attacks a few months ago.

12 people were brutally killed at the offices of the French Satirical magazine a year ago, by two gunmen for angering Islamists due to its irrelevant approach to the religion and for publishing disturbing images of Prophet Mohammed.
