Romani Mourad, a Coptic Christian lawyer, was sentenced on June 1 to one year in prison in absentia and fined 10,000 pounds ($1,430) , also for insulting Islam and the Koran. Two days later, several human-rights groups issued a statement condemning “the rise in numbers of cases” where Copts stood accused of insulting religion.

These “strongly indicate that such cases have become a weapon for religious discrimination and oppression of religious minorities, the groups said.

Egypt’s constitution, approved in a December referendum, has sparked a wave of criticism from activists and human-rights groups, arguing the charter fails to protect human rights. Article 44 in the draft prohibits insulting any prophet.
