PARIS’S Gare de l’Est train station was closed and evacuated after a bomb threat yesterday, as authorities try to prevent new violence after the worst terrorist attacks in decades.

A police official says the station was closed “as a precaution”.

A suspicious package was believed to have been found early yesterday morning.

Le Monde reported a bomb disposal unit was on the ground investigating it. No bomb was found.

The Gare de l’Est is one of several major train stations in Paris, serving cities in eastern Paris and countries to the east.

Meanwhile, the Paris prosecutor’s office says 10 people have been arrested in anti-terrorism raids in the region, targeting people linked to a gunman who attacked a kosher supermarket and claimed ties to the Islamic State.

Admiral Arnaud Coustilliere, head of cyberdefense for the French military, said about 19,000 French websites had faced cyberattacks in recent days, some carried out by well-known Islamic hacker groups.

The attacks, mostly relatively minor denial-of-service attacks, hit sites as varied as military regiments to pizza shops but none appeared to have caused serious damage, he said.

“What’s new, what’s important, is that this is 19,000 sites — that’s never been seen before,” Coustilliere said. “This is the first time that a country has been faced with such a large wave” of cyberattacks.
