The United Nations top envoy to Iraq, seeking support for a roadmap to resolve massive anti-government protests, said Monday that the country’s most powerful Shiite religious leader backs serious reforms but is concerned politicians will not carry them out. At least 12 protesters were also wounded in fresh confrontations with security forces in and around Khilani Square, in Baghdad. Jeanine Hennis-Plasschaert, the U.N. Special Representative to Iraq, met with Grand Ayatollah Ali al-Sistani in the Shiite holy city of Najaf to discuss the series of reforms put forward by the U.N. a day earlier.
