PM Jean Castex sought to assure the parents of the four women and two men that all of France mourned their passing The six, their Nigierien guide and driver, were killed on Sunday in a wildlife haven about an hour’s drive southeast of Niamey PARIS: France’s prime minister led a memorial service Friday for six aid workers killed in Niger in what investigators said had likely been a premeditated attack targeting Westerners. As the six caskets lay side by side in the VIP section of Orly Airport south of Paris, where the bodies arrived Friday from Niamey, Jean Castex sought to assure the parents of the four women and two men that all of France mourned their passing. “In front of these six coffins... I want first of all to express the pain, the incomprehension, the anger of all French people,” said the premier as he saluted the youngsters’ generosity and altruism. “The victims of this attack came to Niger to do good. They met with evil.” The six, their Nigierien guide and driver, were killed on Sunday in a wildlife haven about an hour’s drive southeast of Niamey. The area is a popular destination for weekend leisure trips by Niamey residents, including foreigners. They worked for French NGO Acted and were aged between 25 and 30. “This incarnation of evil, France unfortunately knows it only too well... it is very likely the same hatred, the same cowardice, the same inhumanity at work in Niger and Bataclan,” the Parisian concert venue targeted by extremists in 2015, said Castex. And he stressed there was “no question of giving an inch of ground to criminal fanaticism or to enemies of the freedom to act, think and engage.” Earlier, a source close to an ongoing investigation by French anti-terror prosecutors told AFP the attack “appears to have been premeditated to target a priori mainly Westerners.” France’s anti-terror prosecutor’s office said Monday it would probe charges of murder “with links to a terrorist enterprise” and “criminal terrorist association” in relation to the killings. A team of 11 specialized investigators departed France for Niger the following day. No one has claimed responsibility for the attack carried out by gunmen on motorcycles. But “given the modus operandi, the terrorist hypothesis is being favored,” the source told AFP. Suspicion has fallen on Daesh in the Great Sahara, active in the shared border region of Mali, Niger and Burkina Faso, where it is being pursued by France’s Barkhane force fighting extremists in the Sahel. The French investigation will seek to determine whether the assailants had been tipped off about the humanitarians’ visit to the national park. French President Emmanuel Macron has described it as “manifestly a terrorist attack” and said there would be repercussions. “We’re pursuing action to eradicate the terrorist groups, with the strengthened support of our partners,” Macron said.
