France is tightening security on its vast public transit network after an attack on a high-speed train that was thwarted by a group of Americans, reports CBS News.
The measures announced Monday by France's interior minister, Bernard Cazeneuve, close security gaps that complicated baggage searches and ID checks. The attacker on the Thalys train boarded with a small arsenal of arms in August and had been flagged for links with Islamic extremists.
Three Americans and a Briton subdued him after he tried to open fire in the Brussels-to-Paris train.
Two of the Americans were servicemembers, one in the Air Force and one a a veteran of Afghanistan who had served in the National Guard.
All three were awarded the Legion of Honor by French president François Hollande, and they were personally thanked by President Obama.
Work on new rules began last year but has been accelerated after the Thalys attack.
