PARIS - French President Francois Hollande will reassess security measures once a week all summer, amid fear of new violence after a deadly Bastille Day attack in Nice.

Government spokesman Stephane Le Foll said after a government meeting Saturday that France's leadership is focusing on "adapting itself in all domains" to the evolving threat.

At Saturday's meeting, the French government also discussed the attack on a Munich shopping centre that left 10 dead, and expressed support for the German government.

French investigators are trying to determine whether the Tunisian driver who killed 84 people in Nice on July 14 had direct ties to the Islamic State group, which claimed responsibility for the attack.

Hollande increased military support for Iraq in its fight against IS extremists as a result of the Nice attack.
