BAGHDAD (Reuters) - U.N. Secretary General Ban Ki-moon said on Monday he was concerned about alleged abuses by Iraqi pro-government forces in their war against Islamic State and called for investigations into any wrongdoing.

Ban's remarks, made during a one-day visit to Iraq, amounted to the strongest warning to date by a world leader regarding the suspected conduct of some of the Shi'ite paramilitaries battling Sunni Muslim Islamic State fighters.
