Catholics worldwide held a day of fasting and prayer for peace in Syria joined by Jews, Muslims and Orthodox Christians, with Pope Francis set to host a mass vigil on Saturday. Francis has called for a "cry for peace" to rise up around the globe and has said he will attend the four-hour prayer session in St Peter's Square.
