More than 100 militants from the Islamic State group carried out a complex attack on Syria s largest prison holding suspected extremists, officials said Friday, as members of the group in Iraq stormed an army barracks, killing 11 soldiers as they slept.
The prison break in Syria is believed to be the largest since the militants lost the final sliver of territory they held nearly three years ago. In recent months, IS sleeper cells have become more active in both countries, claiming attacks that killed scores of Iraqis and Syrians.
