Paris police evacuated the Gare de l’Est train station today after a bomb threat, as authorities across Europe pressed on with efforts to prevent new violence after the worst terrorist attacks in decades.

About 30 people were slightly injured today when a commuter train slammed into a buffer at the end of the tracks at the Gare de l’Est train station in Paris, French railway officials said.

Some 2,000 angry students massed on railway tracks in Paris today, stopping international train traffic in a new push to force a contested youth labour law off the books.
