Reuters: Islamic State fighters have executed at least 400 people in Palmyra since capturing the ancient Syrian city four days ago, Syrian state media said on Sunday.
It was not immediately possible to verify the account, but it was consistent with reports by activists that the Islamist fighters had carried out executions since capturing the city from government troops.
BBC News: The United Nations says it has received reports that Syrian forces in Palmyra prevented civilians from leaving, ahead of its fall to Islamic State militants.
The UN, though not present in Palmyra, cited “credible sources”.
It said it was “deeply concerned” about the plight of civilians remaining in Palmyra, amid reports of summary executions.
