CAIRO — The Islamic State (IS) is remobilizing in southern and central Libya, penetrating towns where lawlessness, tribal tensions and poverty are rife. No longer able to seize large swaths of land, the group is waging an insurgency to weaken the country’s competing authorities. The strategy is working, though experts and fighters from the western port city of Misrata, do not expect IS to reclaim the power it had in 2016.
The aspiring caliphate has a personal vendetta with Misrata after forces from the city — united under the banner of Al-Bunyan Al-Marsous (BAM) — defeated IS in the southern city of Sirte in December 2016. US airstrikes, which supported the forces, were vital to the mission.
