Sectarian tensions are increasing  in Iraq, which saw its deadliest day of bombings last weekend, with 60 Sunni Muslims  killed in attacks across Baghdad. Mass protests have erupted over recent months among Sunni groups, who fear they are being marginalised by Nuri al-Maliki's Shia-dominated government.
