BAGHDAD, Jan 6 (Reuters) - Iraqi Prime Minister Nuri al-Maliki said on Saturday Saddam Hussein's execution was a "domestic affair" and warned countries which have criticised the hanging that his government could review relations with them. Maliki, a Shi'ite, said in a speech marking Army Day that Saddam had received a fair trial and that his execution was for the benefit of Iraq's unity. A clandestine video showing images of Shi'ite officials taunting Saddam on the gallows has angered his fellow Sunni Arabs and increased sectarian tension.
