Thirteen nuns who were kidnapped from their monastery north of Damascus last December were released in March in an apparent exchange for prisoners held by the Assad regime. Despite this good news, Christians in Syria continue to be under siege. A jihadist group in the city of Raqqa gave local Christians an ultimatum: convert to Islam, pay a protection tax, or be killed. Although accurate numbers are hard to come by, one estimate says that 450,000 of the 2 million Syrian refugees are Christians. Syrian Christians who have fled their war-torn country report kidnappings, murders, ransacking of their shops, and pressure to convert (Christian Science Monitor, March 10).
