ISIS Kills 20 Men at Palmyra Site

A monitoring group says Islamic State militants have killed 20 men at the ancient theatre inside the Unesco World Heritage site of Palmyra in central Syria.
The Syrian Observatory for Human Rights says residents were rounded up and forced to watch the men being shot.
The group says about 240 people - mostly soldiers - have now been killed by IS since it overran the town last week.
The killings come as there are fears that IS may destroy the 2,000-year-old Roman-era ruins.
