ISIS is reported to have taken 400 civilians as 'human shields' as they prepare to leave their stronghold of Raqqa in Syria.
Jihadist Islamic State militants are said to be 'hours away' from a crushing defeat - but they are reportedly attempting to use the civilians as a bargaining tool.
The U.S.-led coalition however said it wanted the unconditional surrender of all IS militants in Raqqa.
Its spokesman said around 100 jihadist fighters had surrendered in Raqqa in the last 24 hours and had been "removed from the city", and it still expected difficult fighting "in the days ahead".
YPG officials said the Syrian city could be cleared of jihadists by tomorrow at the latest following a major offensive launched in June to oust the extremists.
