Iraq’s parliament approved the resignation of Prime Minister Adel Abdel Mahdi’s cabinet on Sunday, after two months of violent unrest.

Iraq’s prominent Shia cleric Grand Ayatollah Ali al-Sistani has called on politicians and legislators to speed up reforming electoral laws, warning that nothing but the changes can resolve weeks of protests in the capital Baghdad and some southern cities.

 Iraqi premier Adel Abdel Mahdi will travel to Iran on Saturday, a member of his office said, in his first official visit to the country rivalling Washington for influence over Baghdad.
