Across Europe, security officials have been raising the alarm over the return of European jihadis from Syria and Iraq. But a spate of seemingly random rampages in France has drawn attention to attacks that don't amount to organized terrorism, yet still sow terror.聽

On Monday evening, a driver rammed his van into a busy Christmas market in the western city of Nantes, injuring ten people before stabbing himself, though not fatally. The previous day,聽a man injured 13 people in the eastern city of Dijon by running into pedestrians at various points of the city while crying 鈥淕od is great鈥� in Arabic. Authorities say both attackers had a history of mental illness.聽

And on Saturday the same cry was uttered, this time by a Muslim convert who stabbed two policemen in Joue-les-Tours. They were not killed but the attacker was shot dead by police. A terrorism case has been opened in that incident.

Authorities say the three attacks were unrelated.聽Prime Minister Manuel Valls today urged聽the French to stay calm. 鈥淭he events are serious and worrying,鈥� he said on Europe 1 radio. 鈥淓ven if there鈥檚 no link between them I can understand the concern of citizens.鈥�

However, the fact that lone-wolf attackers struck in three locations on three consecutive days is a stark reminder of Europe's jitters over聽homegrown terrorism threats.

French President Fran莽ois Hollande called an emergency cabinet meeting to address the threat. And the government has dispatched up to 300 additional soldiers to patrol public spaces over the holiday season, including Paris's most famed street, the Champs-Elysees,聽where the city's biggest Christmas market is underway.聽

As it steps up its role in the US-led bombing campaign against Islamic State militants, France arguably faces the highest threat from returning jihadis: Officials estimate that around 1,000 French citizens have either聽traveled to Syria or made plans to go. Mr. Valls has called that threat 鈥渦nprecedented.鈥澛�

France has Europe鈥檚 largest Muslim population. It is also actively been targeting Islamist strongholds in Africa. Algeria said Tuesday that of a militant group that captured and killed a French hiker in September. 聽

France鈥檚 interior minister,聽 Bernard Cazeneuve, said that the latest attack in Nantes did not appear to be religious or political. The third case in Tours could have been inspired by radical fanaticism, in the name of religion, but the motives are still unclear, he said.聽

But in any case, France is on edge, in part because a series of senseless attacks without clear motivations are just as alarming as revenge attacks by militant groups.聽

鈥淲e鈥檙e reacting with determination and cool-headedness,鈥� Valls said. 鈥淧eople need to go about their daily lives while remaining vigilant.鈥�
