A local source in Kirkuk province said on Monday, that the so-called ISIS executed three youths in the district of al-Hawija southwest of the province.

“Today, ISIS elements executed three young men for writing slogans and banners against the leader of ISIS Abu Bakr al-Baghdadi which demands the ISIS elements to get out of Hawija (55 km southwest of Kirkuk),” the source said.

The source added, “ISIS threatened whoever writes banners or cooperates with the security authorities and hanged the heads and bodies of the youths in a public square.”
