France raises threat level, giving security forces additional powers

France raised its security threat to the highest alert level, strengthened border controls and asked people around Strasbourg to stay put as and police searched for the suspect. German police also tightened border controls across the Rhine river, officials said. Just over one year ago, President Emmanuel Macron lifted the state of emergency that was imposed across France after the 2015 terrorist attacks in Paris. It was replaced with anti-terrorism laws and a strong police and military presence was maintained, with up to 10,000 troops patrolling and thousands more in reserve. FRANCE 24’s François Wibaux explains what the latest alert level means and what powers it gives on the security forces.
