Rebel infighting kills at least 630

The violence pits rebel groups, including the al Qaida-affiliated Nusra Front, against the Islamic State of Iraq and the Levant, which was disavowed by the terrorist network earlier this year because of its brutality.
The infighting has been a massive drain on resources and manpower for the opposition in Syria, undermining its fight against president Bashar Assad in the wider civil war.
The Britain-based Syrian Observatory for Human Rights said the fighting in Deir el-Zour alone has killed 634 since April 30. It said the tally includes 39 civilians, 354 rebel fighters, including many from the Nusra Front, and 241 gunmen from the Islamic State.
Once spread across much of northern Syria, the Islamic State withdrew many of its far-flung fighters to its stronghold in the northern city of Raqqa earlier this year after other rebel factions, furious with the Islamic State's efforts to impose its hardline interpretation of Islam, launched an offensive against the group.
But the Islamic State has consolidated its hold on Raqqa and the surrounding province, then in early May, its fighters pushed into the neighbouring province of Deir el-Zour, capturing villages and towns along the Euphrates River and closing in on the provincial capital, the city of Deir el-Zour.
