ISIS brutally subdues rebellion in Syria, beheading and crucifying tribesmen who resisted their rule

BEIRUT — Islamic militants have crushed a tribal uprising against their rule in eastern Syria after three days of clashes in a string of villages near the border with Iraq, beheading and crucifying opponents along the way, activists said Monday.

The fighters from the Al-Qaeda breakaway Islamic State group control huge swaths of territory in eastern and northern Syria and are fighting rival rebels, Kurdish militias and the Syrian army for more territory.
