Peshmerga forces with air support from the US-led coalition forced the attackers to retreat and were able to launch a successful counter-attack, the source at Mount Shingal said on Friday.
At least one Peshmerga fighter was killed by ISIS during the attack, according to the source who estimated that dozens of Islamic State fighters were killed during the battle.
In recent months, Shingal has been struggling to recover from a devastating ISIS attack last year that unleashed a spree of killings, rapes and kidnappings against the area's predominantly Kurdish Yezidi population.
The region is still marred by sporadic assaults from ISIS against Peshmerga and other Kurdish forces protecting the area.
