French President Francois Hollande today kicked off a week of commemorations marking the jihadist rampage in Paris that began with an assault on satirical weekly Charlie Hebdo and lasted three days, claiming 17 lives. The president and mayor unveiled a plaque at the Hyper Cacher, in an eastern suburb where four Jews -- three shoppers and an employee -- were killed during a horrifying hostage drama. / AFP / POOL / IAN LANGSDON/POOL
