Another recent uptick in attacks attributed to the Islamic State (IS) in the long-problematic Diyala region northeast of Baghdad near the Iranian border has raised questions about security in the region, while many warn of worsening sectarian tension there and elsewhere.
A Shiite sheikh from the Bani Kaab tribe who was reportedly active in the fight against IS near Khailaniyah in the Muqdadiyah area of Diyala was killed on Oct. 27 along with four of his relatives. The sheikh was said to have been beheaded, while his body was rigged with explosives that then killed those who had come to retrieve him.
