Egyptian authorities have detained two Coptic Christian activists suspected of posting anti-Islamic messages on a Christian website.

Lawyers for Adel Fawzi and Peter Ezzat say security officers arrested the two at their homes in Cairo on Wednesday.  Police sources confirmed the arrests.

Fawzi and Ezzat are senior members of the Cairo branch of the Canada-based Middle East Christian Association. 

It was not immediately known which web postings led to their arrests.

Copts make up about 10 percent of Egypt's population and generally live in peace with majority Muslims.
