Excerpt:
Cartoonist Luz, who drew Charlie Hebdo's front cover picture of Mohammed following the massacre of the satirical weekly's editorial team in January, said Monday he was leaving the paper.
Renald Luzier said his departure in September was unconnected to internal tensions at the publication, but rather that the job without his slain colleagues had become "too much to bear".
"This is a very personal choice," Luz, who joined Charlie Hebdo in 1992, said in an interview with French newspaper Liberation.
