The European Union will not let other nations attack its sovereign borders, France's foreign minister said on Wednesday, responding to comments by U.S. President-elect Donald Trump on taking over Greenland.

Trump declined on Monday to rule out military or economic action as part of his avowed desire to have the U.S. take control of Greenland, as well as the Panama Canal.

French Foreign Minister Jean-Noel Barrot said he did not believe the U.S. would invade the vast Arctic island that has been part of Denmark for over 600 years.

France on Wednesday called on Israel to respect the "sovereignty and territorial integrity" of neighboring Syria and to withdraw its forces from the Golan demilitarized zone between the two countries.

"As stated by the U.N., any military deployment in the buffer zone between Israel and Syria is a violation of the 1974 disengagement agreement which must be respected by its signatories, Israel and Syria," said a French foreign ministry spokesman at a press briefing.

"France calls on Israel to withdraw from this area."

Saboteurs struck France's TGV high-speed train network in a series of pre-dawn attacks across the country, causing travel chaos and exposing security gaps ahead of the Paris Olympics opening ceremony later on Friday.

The coordinated sabotage took place as France mounted a massive security operation, opens new tab involving tens of thousands of police and soldiers to safeguard the capital for the sporting extravaganza, sucking in security resources from across the country.

A Russian chef who has lived in France for 14 years has been arrested on suspicion of plotting with a foreign power to stage “large scale” acts of “destabilisation” during the Olympic Games in Paris.

The 40-year-old man was arrested during a raid of his apartment in central Paris on Sunday where a document linked to an elite Russian special forces unit operating under the command of the FSB, an heir to the KGB, was reportedly found.

In Sunday’s French parliamentary elections, voters delivered a serious shake-up of the status quo, one that now means that, in France, there’s no longer a strong center, but rather a politics increasingly dominated by extremes.

In a surprise triumph over the populist National Rally, France’s left-wing political alliance came first in Sunday’s final round of parliamentary elections. The New Popular Front coalition of leftists won 182 seats, President Emmanuel Macron’s party won 168 seats, and the National Rally and its allies won 143 seats.

French President Emmanuel Macron refused the resignation of the country’s prime minister, asking him on Monday to remain temporarily as the head of the government after chaotic election results left the government in limbo.

French voters split the legislature on the left, center and far right, leaving no faction even close to the majority needed to form a government. The results from Sunday’s vote raised the risk of paralysis for the European Union’s second-largest economy.

A left-wing alliance has won the most seats in the French parliament after tactical voting in Sunday’s second round election thwarted Marine Le Pen’s far-right party, but France will be left in political limbo after no party came close to winning an absolute majority.
