Syrian Kurdish-led fighters take Hajin, final ISIS-held town

U.S.-backed, Kurdish-led fighters captured the last town held by ISISon Friday, after three months of ferocious battles in the militants' single remaining enclave in eastern Syria, activists and Kurdish officials said.

The fall of Hajin marks an end to the extremist group's hold over any significant urban area, which in three years shrunk from the large swaths of Iraq and Syria the militants once held to this small enclave near the two countries' shared borders.

The capture of Hajin, however, does not mark the end of the group, which still holds some villages nearby and has a scattered presence and sleeper cells in both countries.

As the offensive by the Kurdish-led Syrian Democratic Forces intensified over the past days under the cover of airstrikes by the U.S.-led coalition, ISIS fighters withdrew south to areas east of the Euphrates river and west of SDF positions along the border with Iraq.

Among the villages still held by extremists in the enclave are Sousa, Buqaan, Shaafah, Baghouz and Shajla.

The latest push has also raised questions about the fate of ISIS leader and founder Abu Bakr al-Baghdadi, who has not been seen in public since he announced his self-styled caliphate in 2014 from a mosque's pulpit in the Iraqi city of Mosul. Last month, ISIS suffered a severe blow when the SDF said it captured Osama Owayed al-Saleh, a top aide to al-Baghdadi.

"It is a very difficult battle," SDF spokespersonMustafa Bali told The Associated Press by phone from Syria where he said ISIS fighters are still attacking Hajin.

He added that most of the ISIS fighters besieged in the enclave are among the most experienced gunmen who came to the area from Iraq and Syria.

"There are still villages to be taken but Hajin was the most important as it was the base for commanders from where they directed military operations," Bali said.

Ferocious 3-month offensive

Iraqi Maj. Gen. Qassem Mohammed, in charge of operations in areas close to the Syrian border, said artillery strikes by the U.S.-led coalition on the Iraqi side of the border targeted Hajin and areas around it.

The Britain-based Syrian Observatory for Human Rights said the SDF took Hajin early in the morning. It said some ISIS fighters withdrew to nearby villages and that fighting is still ongoing in fields outside Hajin as SDF fighters chase out the extremists.

Europe-based activist Omar Abu Layla of the DeirEzzor 24 monitoring group confirmed that the town had been recaptured, adding that some ISIS fighters are still holed up in small pockets on the edge of Hajin.

Abu Layla said that disagreements among ISIS ranks over hierarchy between Iraqi and Syrian fighters helped "speed up the collapse" of the extremist group's defences in Hajin.

Nuri Mehmud, spokespersonof the Syrian Kurdish militia known as People's Protection Units, or YPG, also the main component of the SDF, said "intense fighting" is still ongoing in small parts of Hajin.

The area is home to some 15,000 people, including 2,000 ISIS gunmen who fought back with counteroffensives and suicide attacks. Over the past days, hundreds of civilians were able to flee the enclave toward areas controlled by the SDF east of the Euphrates and government-controlled regions on the river's west bank.

The observatory said that since the SDF offensive began on Sept. 10, 922 ISIS gunmen, 539 SDF fighters and 324 civilians have been killed.
