BAGHDAD: The mayor of a remote, ISIS-held town in western Iraq says some 200 residents are detained by the group after clashes there.

Trouble in Rutbah, in Anbar province, started Saturday when ISIS militants killed a local resident for killing a member of the group as part of a long-running blood feud. Hundreds of residents demonstrated later on that day to protest the killing and clashes broke out when the militants attempted to disperse the protesters.

A provincial Anbar official said Saturday some 70 residents were detained by the militants and more than 100 more were tied to streetlight poles for about 24 hours as a punishment.

Rutbah's mayor, Imad al-Rishawy, said Monday that around 200 residents are still held by ISIS at an unknown location.
