The main group made a break last night, trying to head North toward ISIS lines, reportedly with a herd of 500 human shields (likely many members of prominent families). Basically, they slipped around the front line of guys shooting at them using tunnels - but they are still in the urban area.
Crossing the open country will be a big challenge, and no one from Manbij is likely to trust ISIS to release their hostages if they are allowed to make it to their lines with them. Unless they are given free passage to release hostages, death continues to close in.
