OMAR OIL FIELD, Syria: 鈥淟arge numbers鈥� of civilians remain inside the last Daesh group enclave in Syria prompting a fresh delay in a final advance, Kurdish-led forces said on Saturday.

鈥淭here are still civilians inside in large numbers,鈥� US-backed Syrian Democratic Forces spokesman Adnan Afrin said on the day President Donald Trump said he expected to announce the end of the militants鈥� 鈥渃aliphate.鈥�

鈥淲e weren鈥檛 expecting this number, otherwise we wouldn鈥檛 have resumed the campaign four days ago. This is why it鈥檚 been delayed,鈥� Afrin said.

A second SDF spokesman said that the diehard militants remained in control of the tiny enclave around the village of Baghouz on the north bank of the Euphrates river.

鈥淭he pocket inside Baghouz is still controlled by the Daesh group,鈥� spokesman Mustefa Bali said.

鈥淭here are still civilians inside Baghouz and we are working on getting them out.鈥�

Neither spokesman would comment on the timeline set by Trump for a US announcement that the 鈥渃aliphate鈥� had been eradicated.

鈥淲e have a lot of great announcements having to do with Syria and our success with the eradication of the caliphate and that will be announced over the next 24 hours,鈥� Trump told reporters at around 1600 GMT on Thursday.
