French President Francois Hollande called today on authorities to exercise the "utmost vigilance" after two men reportedly shouting "Allahu Akbar" committed brutal weekend attacks against police and passers-by in separate towns.
Speaking at the weekly cabinet meeting, the president also urged the French not to "panic", government spokesman Stephane Le Foll told reporters.
France is reeling from the attacks, which saw a man killed on Saturday when he assaulted police officers in the central town of Joue-les-Tours and a driver plough into pedestrians Sunday in Dijon in the east, leaving 13 injured.
Both men reportedly shouted "Allahu Akbar" ("God is greatest") prompting speculation the assaults were motivated by radical Islam.
But Interior Minister Bernard Cazeneuve today urged people to show restraint and calm, and not to jump to conclusions.
Speaking about the second attacker in Dijon, a former psychiatric patient who was arrested after his rampage today, he said his "motives are not established."
