Engel also witnessed a firefight -- a confrontation between his captors and Syrian rebels manning a checkpoint -- that led to his freedom and the death of two of his captors.
"While we're obviously very happy, there are people who are still not at liberty to do this kind of thing. There are still hostages and there are still people who don't have their freedom inside Syria and we wish them well," Engel added.
