Syrian church officials say 2 Aleppo-based bishops who were kidnapped remain missing

Syrian church officials say they have no information on the whereabouts of two bishops who were kidnapped in northern Syria.

The Damascus-based Greek Orthodox Bishop, Tony Yazigi, had told reporters on Tuesday that the bishops, both based in the northern city of Aleppo, had been released.

But later on Tuesday, the Syrian Orthodox Patriarchate in Damascus said in a statement that it had not received "any official document indicating the (bishops') release." The statement was posted on the Patriarchate's website.

Bishop Boulos Yazigi of the Greek Orthodox Church and Bishop John Ibrahim of the Assyrian Orthodox Church were abducted on Monday while traveling outside Aleppo. Gunmen pulled them from their car and shot and killed their driver.

It was not clear who abducted the priests and who is holding them.
