Secretary-General Ban Ki-moon says it's "imperative" that Iraqi security forces stay out of the political process leading to the formation of a new government.

Ban criticized leaders in Iraq and many other places for failing to promote an inclusive society, allowing groups including the Islamic State to take root.

The U.N. chief said "the poison of hatred and brutality" has been allowed to spread in Iraq, Syria and the region. He spoke at a news conference Tuesday.

Ban expressed appreciation for efforts by the United States and some European countries to help the Iraqi and Kurdish governments prevent the further spread of the Islamic State group.

He urged the international community to do more to protect Iraq's minority Yazidi community, especially those trapped on Mount Sinjar.
