BAGHDAD (AP) — Iraq’s Shiite-led government should do more to address complaints by the country’s disaffected Sunni minority about human rights violations and lack of due process, the U.N. envoy to the country said in an interview Monday.

Sunnis have staged mass rallies in recent weeks to protest what they see as unfair treatment of their sect by the government of Nouri al-Maliki, a Shiite accused by critics of monopolizing power.
