The French Embassy in Manila extended condolences Monday to the family of the 23-year-old German-Filipino tourist who was stabbed to death near the Eiffel Tower in Paris on 3 December, in what the French government described as a "terrorist attack".

"Yesterday in Paris, a terrorist attack happened and a man was stabbed to death. He was a tourist with German-Filipino nationality," French Ambassador to the Philippines Marie Fontanel said in a post on X (formerly Twitter).

"On behalf of the French government, I wish to address my deepest condolences to his family and relatives and to the Filipino and German people," Fontanel added.

In a separate statement, the French Ministry of Foreign Affairs also extended its condolences to the Philippines and Germany over the tragic death of a young tourist in France late Saturday.

"Having learned of the victim's dual nationality, France extends its condolences to his family and loved ones, to the Filipino people and to the German people," the ministry said.

According to the French anti-terrorist prosecutors, the attacker who stabbed the victim to death swore allegiance to the Islamic State group in a video posted to social media.

The knife attacker was identified as Armand Rajabpour-Miyandoab, a French national born in 1997 to Iranian parents.

Known to the authorities as a radicalized Islamist who had social media connections to perpetrators of other recent attacks in France, he had also been subject to close psychological surveillance for mental health issues, senior prosecutor Jean-Francois Ricard told reporters.

He added that the man's mother had reported concerns about him as recently as October, but there was insufficient proof at the time to take legal action.

The attack late Saturday came as France is at its highest alert level against the background of the war between Israel and Hamas and following a series of apparent lone-wolf attacks in the country.

Shouting "Allahu Akbar" ("God is greatest"), Rajabpour-Miyandoab fled over the Bir Hakeim bridge across the river Seine after a taxi driver intervened.

Meeting a police patrol on the other side, he claimed to be wearing an explosive belt before running again, striking two passers-by — a 66-year-old British citizen and a 60-year-old French person — with a hammer.

He was finally stopped with two shots from a taser and taken into custody. (WITH AFP)
