“It must be weird for Londoners to read travel advisory from foreign countries against the UK; usually the other way around,” tweeted Gulf social commentator Mishaal Al-Gergawi from a region that has witnessed a lot of civic unrest in the Arab Spring.

Iranian Foreign Ministry spokesman Ramin Mehmanparast said the British government should “exercise restraint,” avoid using violence and instead “talk to protesters and listen to their requests,” the official IRNA news agency said.

For many years Iran has been on the receiving end of criticism from Western countries over its human rights record, especially the crushing of demonstrations after the re-election of President Mahmoud Ahmadinejad in June 2009. A member of Iran’s Parliament, Hossein Ebrahimi, told the semi-official Fars news agency that Britain should allow a delegation of human rights monitors to examine the situation.

The British riots broke out on Saturday in a district of northern London when a protest over the police shooting of a suspect two days earlier led to violence.

The riots in London are the worst violence in the British capital in decades and politicians and police have firmly blamed the violence on criminals and hooligans.

Iran’s state-run news channel led with dramatic pictures of the riots, with one announcer describing the scenes as “civil war.”

An official in Egypt, where unrest earlier this year ousted veteran President Hosni Mubarak, also could not resist making an ironic jab at a Western country that normally prides itself on its respect for the rule of law and for human rights.

“We will send Egyptian NGOs (to London) to check it out,” said the official, in a reference to Westerners who monitored Mubarak’s attempts to quash protests in Cairo’s Tahrir Square.
