Rebels fighting in Syria have given rivals from an al-Qaeda affiliate 24 hours to surrender, according to activists in the country.
Saturday’s ultimatum comes amid days of deadly infighting between opponents of Syrian President Bashar al-Assad and the Islamic State of Iraq and Sham (ISIS) in two northern provinces, Idlib and Aleppo.
The Britain-based Syrian Observatory for Human Rights said rebels from an alliance of religious groups attacked positions of the fighters from the ISIS, killing and capturing dozens of people on Saturday.
The ISIS has been blamed for brutal killings in areas under their control, turning many local residents against them and leading to a growing resistence to the al-Qaeda-linked group’s grip on several areas of the country.
The developments could signal a turning point in the war.
“This is the most serious violence between armed opposition and ISIS,” our correspondent said.
ISIS fighters were reportedly killed in the fighting in Aleppo and nearby Idlib on Friday, while at least 42 other ISIL fighters were wounded in Idlib alone.
Meanwhile, protesters in opposition-held parts of Syria chanted slogans condemning the al-Qaeda affiliate.
Ammar, an activist on the ground, described it as “the start of the revolution against ISIS”, according to AFP news agency.
ISIS and Western-backed rebel forces are all fighting to overthrow the regime of President Bashar al-Assad, but tensions between different groups have been rife in recent months.
Several opposition factions, including a number of fighters united under the name “Army of Mujahedeen”, were involved in Friday’s fighting, according to the Britain-based Syrian Observatory for Human Rights and local activists.
Both the Islamic Front and the Syrian Revolutionaries Front, two key groups made up of tens of thousands of opposition fighters, also condemned ISIS on Friday.
“We call on ISIS to withdraw immediately from Atareb… and remind them that those who freed Atareb [from the Syrian government] are those you are fighting today,” the Islamic Front said.
In Idlib, 20 civilians were injured in the fighting, while a media activist was killed in Aleppo, AFP reported.
The fighting comes two days after ISIS reportedly tortured and murdered a leading opposition figure, doctor Hussein al-Suleiman, known as Abu Rayyan.
His death was the latest in a string of beatings, kidnappings and killings attributed to the group, and prompted protesters to take to the streets under the slogan, “Friday of the martyr Abu Rayyan”.
Amateur video shot in Aleppo on Friday reportedly showed protesters chanting: “Free Syrian Army forever! Crush ISIS and Assad!”
Abu Leyla, an Idlib-based activist, told AFP via the Internet: “I’d say about 90 percent of people in the opposition areas are against ISIS”.
“They use violence and abuses to crush dissent. They are only Islamic in name. All they want is power,” he said.
More than 130,000 people have been killed since the war in Syria broke out in 2011.
