Fear of Spies Spreads Among Syrian Government and Rebel Forces

Some aid workers and journalists no longer trusted

ALEPPO, Syria — Rebel Col. Abduljabbar Aqidi was at his desk in a repurposed school when an assistant came in and slipped him a piece of paper about his plans for the evening.

"Should we go to this operations room, or this one?" the assistant asked cryptically.

Aqidi, who heads the Aleppo Military Council, was planning a dinner with a group of Syrian rebels on the front lines that night. But even here, in the heart of opposition territory, he and his aides were wary of discussing their movements aloud.
