Nonetheless, Marja' Ali al-Sistani issued an "Advice and Guidance to the Fighters on the Battlefields" which included a 20 points form of how the PMF should conduct themselves. The main points were that the PMF should treat the liberated areas locals with the Islamic Law which is as quoted from the second point which is a Hadith of the Muslim Prophet Muhammed; "Do not indulge in acts of extremism, do not disrespect dead corpses, do not resort to deceit, do not kill an elder, do not kill a child, do not kill a woman, and do no not cut down trees unless necessity dictates otherwise". Other points included the same aforementioned guidance when treating non-Muslims and also not to steal or disrespect people even if they are the families of the ISIS fighters. Kata'ib Hizballah, one of the militias of the PMF, is listed by Japan's Public Security Intelligence Agency as a terrorist organization. The United Arab Emirates also classifies it as terrorist. Kata'ib Hizballah was designated a terrorist organization in 2009 by the United States. Its leader, Abu Mahdi al-Muhandis, was also designated a terrorist. Some of the militias constituting the Popular Mobilization Forces have been accused of war crimes motivated by sectarian revenge: according to Amnesty International, Shiite militias have abducted, tortured and killed numerous Sunni civilians and, according to Western sources, in Tikrit militants have committed some violences, while being publicily praised; On the wake of the conquest of Tikrit, Iraqi authorities declared that war crimes will be investigated and their perpetrators punished. High Iraqi Shiite authorities, such as Grand Ayatollah Ali al-Sistani or Ayatollah Hussein Al-Sadr, called on the militants in the popular mobilization forces to avoid war crimes or other despicable behaviour and "ad hoc" government inquiry committees have been established in order to find the truth. Mosul Sunni dignitaries and officials accuse PMF of killings of Sunnis, takeovers of schools and the forcing of Sunnis to sell property in the prime real estate area close to the Mosul shrine. According to City council's deputy chairman Muzher Fleih, 650 Sunnis have disappeared. On the other hand, militia leaders insist any abuses are isolated incidents, and target only captured Islamic State's collaborators. Alongside war crimes accusations, also some concerns regarding constitutionality and politicization of al-Hashd al-Shaabi have been raised: Sunni sources have called for depoliticization of the Popular Mobilization Forces, to be achieved under the proposed National Guard bill.
