Paris: The French satirical newspaper whose staff was decimated in an Islamist attack will come out as scheduled next week, one of its surviving staffers told AFP on Thursday.

Charlie Hebdo will publish next Wednesday to defiantly show that "stupidity will not win," said columnist Patrick Pelloux, adding that the remaining staff will soon meet.

"It's very hard. We are all suffering, with grief, with fear, but we will do it anyway because stupidity will not win," he said.

He added that the publication would have to be put together outside Charlie Hebdo's headquarters, which were not accessible following the massacre.

Twelve people, including five cartoonists, were killed in Wednesday's attack that also left two policemen dead.
