The Libya Channel website has more information about IS's capture of the Libyan town of Sabratha yesterday.
Libya Channel says that IS briefly overran the center of the town after three of its militants were captured by a rival militia. Some of the IS militants later returned to their bases but one source said IS still has a significant presence in the town.
IS militants -- mostly Tunisians, according to local witnesses -- took over the al-Khataba district in the center of Sabratha where they met no resistance.
“No one stopped them from taking over, we were worried what they would do,” one local told Libya Channel.
“Most of the fighters seemed to be from Tunisia,” he added.
Libya Channel adds:
According to Libya Channel sources, closed door meetings took place Thursday afternoon between IS militants and the town’s municipal council to resolve the crisis, as people feared a complete takeover.
After successful negotiations IS returned to their bases.
“The three prisoners were handed back to IS in exchange for them leaving the heart of the city,” said another source.
“But they still have a significant presence in the town,” he said.
