President Emmanuel Macron announced Thursday that France would send Mirage 2000 fighter jets to Ukraine, in what would appear to be a significant increase in his country’s direct military support to Kyiv.

“Tomorrow we will launch a new cooperation and announce the transfer of Mirage 2000 [jets], which help Ukraine protect its skies,” Macron said during an interview with broadcaster TF1 in the northern city of Caen, coinciding with the start of an official visit by Ukrainian President Volodymyr Zelenskyy.

The French president also said Ukrainians would receive training in France for five to six months as early as this summer, with a target of training 4,500 service personnel.
