BEIRUT (AP) -- U.S.-backed and Kurdish-led Syrian forces said Saturday they have launched a final push to defeat the Islamic State group in the last tiny pocket the extremists hold in eastern Syria.
Syrian Democratic Forces spokesman Mustafa Bali tweeted that the offensive began Saturday after more than 20,000 civilians were evacuated from the ISIS-held area in the eastern province of Deir el-Zour. An SDF statement said the offensive was focused on the village of Baghouz.
The SDF, backed by U.S. air power, has driven ISIS from large swaths of territory it once controlled in northern and eastern Syria, confining the extremists to a small pocket of land near the border with Iraq.
Scores of ISIS fighters are now besieged in two villages, or less than 1 percent of the self-styled caliphate that once sprawled across large parts of Syria and Iraq. In recent weeks, thousands of civilians, including families of ISIS fighters, left the area controlled by the extremists.
"The decisive battle began tonight to finish what remains of Daesh terrorists," Bali said, using an Arabic acronym to refer to ISIS.
"The battle is very fierce," he later told The Associated Press. "Those remaining inside are the most experienced who are defending their last stronghold. According to this you can imagine the ferocity and size of the fighting."
Bali did not say how long they expect the battle to last.
