PARIS >> French President Emmanuel Macron decried his Nazi-collaborator predecessors and rising antisemitism, vigorously vowing to stamp out Holocaust denial as he paid homage Sunday to thousands of French children sent to death camps 80 years ago for one reason: because they were Jewish.

Family by family, house by house, French police rounded up 13,000 people on two terrifying days in July 1942, wresting children from their mothers’ arms and dispatching everyone to Nazi death camps. France honored those victims this weekend, as it tries to keep their memory alive.

For the dwindling number of survivors of France’s wartime crimes, a series of commemoration ceremonies Sunday were especially important at a time of rising antisemitism.

A week of ceremonies marking 80 years since the Vel d’Hiv police roundup on July 16-17, 1942 culminated Sunday with an event led by Macron, who pledged that wouldn’t happen ever again.
