Frustratingly vague accounts indicate that a contingent of US Special Forces sent to fight ISIS in Libya were chased off by a local militia. The troops chose to leave "in an effort to avoid conflict," a US Africa Command spokesman told the BBC, but doesn't tell us much about the hostile militia. Stars & Stripes says the US troops were sent to an airbase near the ISIS-held town of Sabratha, in Libya's west, but doesn't tell us which of the country's rival regimes controls the base. Libya Herald names the base as al-Wattiyah, controlled by forces loyal to the government of Prime Minister Abdullah al-Thinni. That is the internationally-recognized government, based in the eastern city of Bayda, with its parliament in Tobruk. Sabratha and al-Wattiyah are actually west of Tripoli, seat of the Libya Dawn coalition that controls most of the country's west, but appears to be a western pocket loyal to the Thinni government—now threatened by ISIS. It appears uncertain if the hostile militia was ostensibly loyal to the eastern regime. Representatives of the rival regimes signed a deal in Morocco on this week, agreeing to form a national unity government—but the incident at al-Wattiyah indicates how tenuous their actual control of ground forces is, even in areas ostensibly under their control.

Catholic Online meanwhile reminds us that Sabratha is the site of a third-century Roman amphitheater and UNESCO World Heritage Site, raising fears that it could be destroyed or plundered by ISIS forces.
