Iranian official urges Britain to allow delegation into country to investigate police human rights violations.

As riots have spread across the UK leading to hundreds of arrests and the death of one 26-year-old man, Iran has called on British police to avoid using violence against rioters and demonstrators, and to show “restraint” when dealing with protesters, Iranian Fars News Agency reported.

The Iranian Foreign Ministry Spokesman Ramin Mehman-Parast reportedly asked the UK government to open dialogue with “protesters,” and has called on human rights groups to investigate the killing of Mark Duggan, 29, which sparked the violent riots that has seen substantial damage and theft.

If something is worth doing at all, it’s worth doing well, so Iran’s delegation is privately offering to share its longstanding experience in torture, rape, mutilation, murder and kangaroo courts with Britain, which never has had a particularly good grip on how to violate human rights properly.
