Charlie Hebdo, the irreverent French magazine, is to be sued by the Abu Dhabi-based Muslim Council of Elders, according to a tweet on the account of the Sunni institution Al-Azhar, based in Cairo, because of its repeated publication of images of Muhammed.

The Council is not the only Muslim entity to say it will sue the magazine. President Erdogan of Turkey is also extremely unhappy about the publication’s latest front cover, which has a cartoon of the Turkish leader in his underwear and holding a can of beer and lifting the traditional dress of a female carrying drinks.

The caption reads: “In private, he is quite amusing.”

Relations between France and Turkey have soured in recent weeks. Erdogan said that President Macron needed mental health tests and France withdrew its ambassador after the slight.
