(CNN) Public beheadings. Corpses hanging from scaffolding. Floggings for violating the law.

This is life in the ISIS-held city of Sirte, Libya -- a Mediterranean coastal city that's about 350 miles away from Malta -- according to a new report from Human Rights Watch.

Many of the 45 former and current residents of Sirte Human Rights Watch spoke to say they live in a continued state of fear.

"As if beheading and shooting perceived enemies isn't enough, ISIS is causing terrible suffering in Sirte even for Muslims who follow its rules," said Letta Tayler, a senior terrorism and counterterrorism researcher at Human Rights Watch.

"While the world's attention is focused on atrocities in Syria and Iraq, ISIS is also getting away with murder in Libya."
