Iranian Foreign Ministry spokesman Ramin Mehmanparast called on UK Police to exercise restraint and behave in a controlled way while dealing with public protests. In reaction to the massive public protests in Tottenham, Mehmanparast urged the British police to stop violent confrontation with the people protesting over the killing of a black man in London. He underlined the need to start negotiations with the protesters and listen to their demands in order to calm down the situation and bring about peace and tranquility, Iranian (IRNA) News Agency reported. He called on independent human rights organizations to investigate the killing of a man in line with safeguarding the civil rights. The unrest began on Saturday when a few hundred people gathered outside a police station in Tottenham to protest against the fatal shooting of Mark Duggan on Thursday. The protesters also set a bus and buildings on fire on High Road and broke many shop windows. Turmoil is now threatening to sweep across all of Britain as the mayhem and looting has also spread to the central city of Birmingham, the western city of Bristol, the northwestern city of Liverpool, and south London neighborhood of Brixton.
