Kurdish militia pressed a big offensive against Islamic State in northeast Syria on Wednesday, cutting one of its supply lines from Iraq, as fears mounted for dozens of Christians abducted by the hardline group that recently beheaded 21 Egyptian Copts.
The Syriac National Council of Syria says Islamic State seized 150 Assyrian Christians from villages in Hasaka province in a mass abduction coinciding with the offensive in the same region by Kurdish forces backed by U.S.-led air strikes.
Hundreds more Christians have fled to the two main cities in Hasaka province, according to the Syriac council and the Syrian Observatory for Human Rights, which is tracking the conflict.
Islamic State has killed members of religious minorities and Sunni Muslims who do not swear allegiance to its self-declared “caliphate.” The group last week released a video showing its members beheading 21 Egyptian Coptic Christians in Libya.
The abductions in Syria follow advances by Kurdish forces against Islamic State in areas of the northeast near the Iraqi border - an area of vital importance to the group as one of the bridges between land it controls in Iraq and Syria.
“They want to show themselves strong, playing on the religion string, at a time when they are being hit hard,” said Rami Abdulrahman, who runs the British-based Observatory, speaking by telephone.
The Syrian Kurdish YPG militia, backed by U.S.-led air strikes, last month drove Islamic State from the Syrian town of Kobani, since when further signs of strain have been seen in the group's ranks.
The Assyrian Christians were taken from villages near the town of Tel Tamr, some 20 km (12 miles) to the northwest of the city of Hasaka. There has been no word on their fate. There have been conflicting reports on where the Christians had been taken.
“These were peaceful villages that had nothing to do with the battles,” said Nasir Haj Mahmoud, a Kurdish official in the YPG militia in northeastern Syria, speaking by telephone from the city of Qamishli.
Some Christians are fighting under the umbrella of the YPG in Hasaka province, but not in that area, he added.
Kurds inflict new losses on Islamic State
The new Kurdish offensive launched over the weekend was focused on dislodging Islamic State from areas some 100 km (60 miles) further to the east, including Tel Hamis, a town that is one of its strongholds.
The Observatory said at least 132 Islamic State fighters had been killed in the fighting since Feb. 21. Mahmoud, the Kurdish official, said seven members of the Kurdish YPG militia had been killed, including one foreigner.
In a telephone interview from the city of Qamishli, he said the YPG had cut a main road linking Tel Hamis with al-Houl, a town just a few kilometers from the Iraqi border.
“This is the main artery for Daesh,” he said, using an acronym for Islamic State. The Kurdish YPG militia had seized more than 100 villages from Islamic State in the area, he added.
“We believe we will finish the battle of Tel Hamis in this campaign,” he added.
The offensive underlines the emergence of the well-organized Syrian Kurdish militia as the main partner for the U.S.-led alliance against Islamic State in Syria.
Mainstream rebels fighting President Bashar al-Assad have mostly been eclipsed by jihadists, complicating a U.S. plan to train and equip Syrian opposition forces to fight Islamic State.
Washington has shunned the idea of partnering with the Damascus government, seeing Assad as part of the problem. Syrian government forces, waging a separate campaign against Islamic State, have made advances against the group in Hasaka in recent weeks.
The latest fighting in Hasaka is one piece of the Syrian war that is about to enter its fifth year and is being fought by an array of forces on multiple frontlines.
Government forces and allied militia are waging their own campaign against Islamic State, while also battling other insurgents in western areas that are mostly under state control.
The U.S. Central Command said last week that an Iraqi and Kurdish military force of some 20,000 to 25,000 was being prepared to recapture the city of Mosul from Islamic State, probably in the April-May time frame.
