Islamic State member yelled 'Allahu akbar,' killed man in Paris and charged at police with knife

A knife-wielding assailant yelled “Allahu akbar” as he killed a passer-by and seriously wounded four others in the heart of Paris late Saturday before he was shot dead by police, Reuters news reported.

What did he say to police?

Police union representative Rocco Contento told Reuters that following the attack, he rushed at police with a knife shouting “I will kill you, I will kill you!” He was then shot by the officers.

The Islamic State later released a video of a man claiming his alliance to the group’s leader, Abu Bakr al-Baghdadi, according to the report.

The man in the video is believed to be the killer, although his face is covered. In the video, the man speaks in French and tells other members of the extremist group in Germany, France and UK to “stay strong, victory is at hand,” the Daily Mail reported.

He ends the video by looking into the camera and saying "goodbye."

The country has been on high alert amid a series of attacks commissioned or inspired by the Islamic State, Reuters reported. In all, the group is believed to have killed more than 240 people since 2015.

France “will not yield an inch to the enemies of freedom,” President Emmanuel Macron said after the attack. He also praised officers for for their actions.

Police in Paris reported receiving the first emergency call about the attack at 8:47 p.m. Saturday.

Where was he from?

Paris prosecutors confirmed the 20-year-old killer was born in the Russian republic of Chechnya in 1997. He had no previous criminal record but was on an anti-terror watch list of suspected extremists, reports state.

He arrived in France in the early 2000s as a political refugee, and showed an increasing interest in radical Islam, the Daily Mail reported.

There are an estimated 30,000 Chechens in France. Most of them came as political refugees in the early 2000s because of the two Chechen Wars, according to the report.

Ramadan this year runs from Tuesday, May 15, and ends in the evening of Thursday, June 14. In the past, Islamic-led terrorist attacks have happened during Ramadan, a time of fasting and prayer for Muslims. ISIS has also called for more attacks to be carried out during the Ramadan.
