Syrian opposition activists said Daesh militants have regained control of a town near the border with Iraq that the government said it captured earlier this week.

Boukamal, the last major Daesh stronghold in Syria, was taken by government soldiers and their allies on Thursday. Daesh militants withdrew from the town and launched a counteroffensive over the past two days.

Rami Abdurrahman of the Britain-based Syrian Observatory for Human Rights and Omar Abu Laila, a Europe-based opposition activist originally from Syria's eastern province, said Saturday that Daesh fighters are now once again in full control of the town.

There was no government comment.

Syrian regime state TV on Friday aired live footage from inside the town after activists said Daesh fighters retook parts of Boukamal.
