A man who attacked police officers at Notre Dame cathedral pledged support to Islamic State in a video, it has been revealed.
The attack took place in a crowded area in front of the cathedral in the French capital on Tuesday. Another attacker opened fire on a police van on Paris' Champs Elysees in April, killing one and seriously wounding two others.
Farid I., who was shot in the thigh during the incident outside Notre Dame, "has begun to be interviewed by investigators", at the hospital where he is under armed guard, a source close to the enquiry said.
Ikken was shot and wounded by police after he attacked, shouting: "This is for Syria!"
Sofiane Ikken, his nephew, said his uncle expressed complete disdain for Isis as recently as last summer but seemed "a little bit alone" when he last phoned three weeks ago to get family news.
Documents found on the attacker identified him as a 40-year-old Algerian student doing a doctorate on the media at a university in eastern France.More news: UK hails man who fled attack holding beer an unlikely hero

Isis has called for supporters around the world to carry out intensified terror attacks during the Islamic holy month of Ramadan, as it seeks to maintain momentum while losing territory in Syria and Iraq.
The man, a former journalist who was working on a doctoral thesis, can be seen lunging at officers outside the cathedral with a hammer, then being shot to death.
Since 2015, France has been the target of several attacks causing a total of more than 230 dead and hundreds injured.
The video pledging allegiance to the jihadist group was found in a police search of an apartment he was renting in Cergy outside Paris, the source in the investigation said.
French government spokesman Christophe Castaner told RTL radio that police quickly classified Tuesday's hammer attack as a "terrorist act" because of "the words he said". The suspect's thesis director at the University of Lorraine, where he enrolled in 2014, said he had showed "no outward sign of an excessive adherence to Islam". "Nothing unusual had been detected", he said.
"When I knew him, he had a pro-Western, pro-democratic outlook", Mr Arnaud Mercier, who said he had not heard from the suspect since November, told French television channel BFMTV.
