French illustrators have been denounced on social networks in recent days for publishing editorial cartoons inspired by photographs of Aylan Kurdi, a 3-year-old Syrian boy whose drowning in the waters off Greece this month prompted an outpouring of sympathy for refugees.

Most of the outrage has been directed at Charlie Hebdo, the satirical French newspaper that was attacked in January by Islamist militants for cartoons mocking the Prophet Muhammad. The latest edition of the weekly paper, devoted to mocking Europe’s response to the migrant crisis, features a series of cartoons riffing on the harrowing image of the young boy’s body as it was discovered, face down on a beach in Turkey.
