Islamic State successes fuel fear and anxiety
The United Nations says it has received "credible" reports that civilians were prevented from leaving Palmyra by Syrian forces before the city fell to Islamic State (IS) fighters.
There are also reports of executions, and fears for the city's world-famous archaeological treasures.
Meanwhile, in Iraq, thousands of people have fled from Ramadi, which was also captured by IS militants recent days.
