51 rebels killed in Syria

A total of 51 rebels were killed Thursday during an infighting among rival radical rebel groups in east Syria, a media report said citing activists.

The so-called Islamic State of Iraq and the Levant (ISIL) seized control over the city of Bukamal in the oil-rich province of Deir al-Zour in eastern Syria, near the Iraqi borders, following clashes with the Al Qaeda-linked Nusra Front and so- called Islamic Front, Xinhua quoted the report as saying.

The armed militant groups' infighting in Bukamal has killed at least 51 rebels and the death toll is likely to rise, the report said, adding that the Nusra fighters have called up for reinforcement amid intense battles with the ISIL.

The ISIL has recently been fighting against the Nusra Front and the Islamic Front for controlling the Bukamal, which they have captured together from the Syrian government troops before, to control its border point with Iraq's al-Anbar city, which is deemed as one of the ISIL's main strongholds in western Iraq.

The Deir al-Zour province has largely spiralled out of the government control during the country's long-running conflict and recently become a stage for rebels' infighting.
