A Syrian monitoring group says Islamic State (IS) militants have executed at least 217 people in and around the ancient Syrian city of Palmyra since they captured it 10 days ago.
The London-based Syrian Observatory for Human Rights said on May 24 that it has documented the execution by IS fighters of 67 civilians, including 14 children and 12 women.
It said 150 members of Syrian security forces in different parts of Homs Province had also been put to death since May 16.
The security forces's deaths include people accused of being "informers loyal to the regime" of Syrian President Bashar al-Assad.
Observatory Director Rami Abdel Rahman said entire families had been killed.
He added that most of the deaths took place in Palmyra and included both shooting deaths and beheadings.
At least 220,000 people have been killed in the Syrian civil war since it began in March 2011.
