The 5-year-old boy was named Andrew, to honor the British priest who baptized him at St. George's Anglican Church in Baghdad.

 When Islamic State forces moved into Qaraqosh, the boy's parents faced an agonizing choice that has become all too common in the ancient Christian towns of the Nineveh Plain. The choice: Convert to Islam or suffer the consequences. 

Andrew was cut in half, his parents said, while they were forced to watch.

 The traumatized parents were later reunited with Canon Andrew White, long known as the "vicar of Baghdad." This is one of many stories he has been sharing with journalists -- for years he acted as special envoy for the Archbishop of Canterbury -- in an attempt to raise awareness of the hellish details behind the now-familiar television images.

 A recent trip to Washington, D.C., brought him to the Holocaust Memorial Museum, a setting that raised agonizing questions about the massacres carried out by the Islamic State of Iraq and Syria -- which has claimed the power to establish a new Islamic caliphate in the region.
