France to revise security policy after Paris attack: Defence minister

France will revise its security strategy to better respond to terror attacks after a series of shootings and suicide bombings struck the capital city on Friday, Defence Minister Jean-Yves Le Drian said on Sunday.

"The scale of the threat has changed. It has militarized and our defence strategy must be adapted to that. This is a considerable challenge and France will meet it," Xinhua quoted Le Drian as telling local weekly Le Journal de Dimanche.

"After the launch of the Sentinel operation (after attacks on Charlie Hebdo magazine in January), it became necessary to define a new strategy on the use of the country's armed forces," he added.

"Daech (an acronym referring to the Islamic State) is a real terrorist army and we must fight relentlessly everywhere," Le Drian said.

On Friday night, President Francois Hollande declared a state of emergency after the terror attack in which at least 129 people were killed and over 350 were injured.

After the attack, Hollande ordered an additional deployment of 1,500 military officers in Paris to ensure safety of public places.
