At least two people were killed after a gunman claiming allegiance to the terrorist organisation Islamic State (IS) opened fire and took hostages at a supermarket in southwest France on Friday.
According to the media reports, the Gunman is a Moroccan national, who is now alone in the supermarket with the member of French security forces.
French Prime Minister Édouard Philippe said the information suggests it would be a terrorist act.
"Hostage taking underway in Trebes: all the information suggests that it would be a terrorist act. I am shortening my trip to Mulhouse to return to Paris," he tweeted.
Earlier, one officer was injured in a separate incident when a gunman opened fire on a police team from Marseille who were jogging.
However, the two incidents reportedly believed to be linked.
