France Reintroduces EU Border Controls After London Attacks

France reintroduced border controls within the European Union after last week's terrorist bomb blasts in London that killed at least 52 people, Interior Minister Nicolas Sarkozy said through a spokesman.

To authorize the controls, France activated on July 8 a clause in the Schengen agreement, by which EU countries removed controls of their common borders, Sarkozy's spokesman Franck Louvrier said.

Some nations such as the U.K. opted to stay out of the Schengen accord, which also involved the creation of common external border rules.
