Following a fatal attack on a German citizen in Paris, three more people have reportedly been taken into police custody. A suspected Islamist killed the German tourist with a knife in Paris near the Eiffel Tower on Saturday evening, Interior Minister Gerald Darmanin had confirmed on the social platform X. The three people arrested are from the attacker's circle and supposedly include his parents, media reports said on Sunday. Two other people were injured in the attack. Darmanin wrote on X that police had detained the suspected perpetrator. The man was knifed in the back and shoulder and suffered a cardiac arrest, French newspaper Le Parisien reported, citing the police. The attacker then fled and attacked two other people before being detained. A woman with the German tourist was uninjured but had gone into shock, Darmanin said. According to media reports, the perpetrator is 23 years old and has both German and Philippine citizenship. The two persons injured, possibly with a hammer, were a Briton aged 66 and a Frenchman aged 60. Neither is in danger, according to reports on Sunday afternoon. During a visit to the scene of the crime, Darmanin said that the perpetrator was known to the domestic intelligence service for radical Islamism and "significant mental disorders," according to television channel BFMTV. The detained man had reportedly already been sentenced to four years in prison in 2016 following a failed attack plan. French President Emmanuel Macron expressed his condolences to the victim's family, and German Chancellor Olaf Scholz posted on X: "It is once again clear why we must decisively oppose hatred and terrorism." French Prime Minister Elisabeth Borne wrote on X: "We will not give in to terrorism. Never." The French anti-terrorism prosecutor's office announced that it would look into the attack. Darmanin went on to say that the alleged perpetrator had said after his arrest that he could no longer bear to see Muslims die in both Afghanistan and Palestine. The man believed that France was complicit in Israel's war in the Gaza Strip and wanted to die as a martyr. Le Parisien reported that the suspected perpetrator is said to have sworn allegiance to the Islamic State group. Australian Associated Press
