Iran and Libya are chastising Britain about its handling of ongoing riots that have swept through London and other major British cities.

Iranian President Mahmoud Ahmadinejad Wednesday condemned what he called Britain's “savage” treatment of peaceful protesters. He also told reporters in Tehran the British government needs to listen to the demands of the people who have become frustrated.

An official with the government of Libyan leader Moammar Gadhafi also criticized Britain Wednesday, saying that British Prime Minister David Cameron has lost his legitimacy and must step down.

Britain was a leading critic of Iran's treatment of protesters following the disputed June 2009 election that kept Mr. Ahmadinejad in office. British forces have also played a key role in the NATO campaign in Libya, which started after Mr. Gadhafi's government turned on anti-government protesters earlier this year.

Also Wednesday, South Africa's government issued a travel warning for its citizens planning trips to Britain. The Foreign Ministry advised South Africans who are planning non-essential visits to London to postpone their trips.

Spokesman Clayson Monyela says South Africa's government is closely monitoring the situation and that the High Commission in London is prepared to offer assistance to any citizen needing it.
