Iran has called on the British police to exercise restraint against people protesting over the killing of a Black man in London, Press TV reported.
Iranian Foreign Ministry Spokesman Ramin Mehmanparast urged the British government to order the police to stop their "violent confrontation with the people", IRNA reported in the early hours of Tuesday.
Mehmanparast asked the British government to start dialogue with the "protesters" and to listen to their demands in order to calm the situation down.
The Iranian official also asked independent human rights organizations to investigate the killing in order to protect the civil rights and civil liberties.
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.
Over the weekend, the mainly youthful rioters set alight buildings, buses and police cars, attacked officers with sticks, bricks and missiles and proceeded to ransack shops in a looting spree marked by a "shocking level of violence," police said.
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.
Police said they have arrested more than 200 people since the unrest began.
