DAMASCUS, Syria — Rifa was growing frantic. Her husband had called to say that he and her brother were stuck on their way home from work outside the Syrian capital, normally a 25-minute drive. There was fighting in a northern suburb, he said, and traffic was frozen.

Tensions rose as the hours passed. It is never good to be out after dark in Damascus now, especially trapped in a traffic jam, unable to flee. Finally, Rifa’s husband called again. They had escaped and returned to their workplace to pass the night, another concession to their changing world.

War has come to Damascus. Not on the scale of Aleppo or Homs, at least not yet. But the difference from just a few months ago is unmistakable. With sandbagged checkpoints every half-mile and soldiers methodically searching vehicles for weapons, simple movement is becoming impossible.

“Where is Damascus headed? Are we the next Aleppo?” Rifa asked a few days later. “How soon before our city, our markets, are destroyed?”
