The Organization of Islamic Cooperation urged on Saturday an "unconditional" release of two bishops kidnapped this week in Syria.
OIC secretary general Ekmeleddin Ihsanoglu condemned the kidnapping on Monday of Aleppo's Greek Orthodox Archbishop of Aleppo Boulos Yazigi and Syriac Orthodox Archbishop of Aleppo Yuhanna Ibrahim by armed men as they were en route to the northern city from the Turkish border.
He called in a statement for their "immediate and unconditional release because such act contradicts the principles of true Islam, and the [high] status held for Christian clergymen in Islam."
The head of the 57-member organization of states said Christian clergy always "lived in dignity and honor in the countries of Islam."
No group has claimed responsibility for the kidnapping, but sources at the Greek Orthodox Church have said the kidnappers are "Chechen jihadists."
Christians account for around five percent of Syria's population. They have become increasingly vulnerable to attack and abductions in the lawlessness that has engulfed much of the country since an uprising against President Bashar al-Assad erupted two years ago.
