Journalist Peter Theo Curtis returned to the United States on Tuesday, two days after he was released by an Islamist rebel group in Syria, US media reports said. "I have been so touched and moved, beyond all words, by the people who have come up to me today — strangers on the airplane, the flight attendants and, most of all, my family — to say welcome home," Curtis said in a statement released by his family to US media after he arrived in Boston.
