One of Egypt's richest men has been accused of mocking Islam after tweeting cartoons of Mickey and Minnie Mouse wearing conservative Muslim attire.
Telecoms mogul and Coptic Christian Naguib Sawiris apologised for re-posting the images on Twitter a few days ago, saying he meant no offence.
Naguib Sawiris is a leading secularist and recently formed a political party.
But several Islamic lawyers have filed a formal complaint and there are calls for a boycott of his businesses.
The outcry comes at a time of tension between Egypt's Christians and Muslims.
There are also concerns about the growing influence of the ultra-conservative Salafists in Egypt. Salafists take their inspiration from the early generations of Muslims who were close to the Prophet Muhammad and his message.
The tweeted images showed Mickey Mouse wearing a traditional Islamic robe with a full beard, while Minnie Mouse is wearing a niqab - a full-body veil - with just her eyes showing.
She is identifiable by her large ears and trademark pink hair ribbon.
The cartoons were already widely circulating online, but when Mr Sawiris re-posted them last week, he received an immediate angry reaction from people who said they were offended.
