BEIRUT — The military chief of Syria’s main Western-backed rebel group warned Saturday that the country risked a “humanitarian disaster” if allies do not send more aid to help his moderate forces halt the advance of Islamic militants.
Extremist fighters of the Islamic State of Iraq and the Levant control a large area straddling Syria and neighboring Iraq, mostly running across the Euphrates River, where they have established their self-styled caliphate. Most of the land was seized last month in a push across Iraq.
In recent days, fighters from the group have been pushing into rebel-held territory around the northern Syrian city of Aleppo, close to the Turkish border. They are also consolidating their rule along a corridor of land in the eastern Syrian province of Deir el-Zour that leads to neighboring Iraq.
“We call on urgent support for the FSA with weapons and ammunition, and to avoid a humanitarian disaster that threatens our people,” said Brig. Gen. Abdul-Ilah al-Bashir, commander of the Free Syrian Army. “Time is not on our side. Time is a slashing sword.”
His statement underscored the distress of many of the country’s rebel fighters, whose battle to overthrow President Bashar Assad has been overshadowed by the advance of Islamic State fighters.
In northern Syria, where the extremists have been pushing back rebels, Syrian government forces also seized a key industrial area, allowing them to choke off rebel-held parts of Aleppo.
Al-Bashir called on rebel allies, chiefly the United States but also neighboring Turkey and regional supporters Saudi Arabia and Qatar, to speedily send help. He said the Islamic State fighters will not halt at Syria’s borders.
