"This ping pong game was designed by the British government and conducted simultaneously with a visit by one of the leaders of the regional countries to London," Secretary of Iran's Supreme National Security Council (SNSC) Ali Shamkhani said on Monday in reference to the laxity and passivity of UK government and police forces in response to the attack.
A number of attackers scaled the wall of Iran's Embassy building in London on Friday and took down the Iranian flag.
According to the Islamic Republic News Agency, IRNA, British police did nothing to protect the compound during the attack.
Iran on Saturday summoned the British ambassador to Tehran over the attack on its diplomatic mission in London.
"Following an assault by a number of individuals affiliated to an extremist religious group on the Islamic Republic of Iran's Embassy in London, the country's ambassador was summoned by the director general for Europe affairs [at the Iranian Foreign Ministry] today," Iranian Foreign Ministry Spokesman Bahram Qassemi said.
The Iranian spokesperson's comments came a day after he strongly condemned the assault, urging swift action to counter the attackers.
Immediately after receiving news of the assault, Iranian Deputy Foreign Minister for Political Affairs Abbas Araqchi voiced Tehran's strong protest to Britain's ambassador to Tehran, Qassemi said.
Later on Friday, Qassemi said the attackers who had climbed on the balcony of the Iranian embassy in London were arrested, adding the spectacle was over.
He called for the trial and punishment of the perpetrators of the assault.
Iranian Ambassador to London Hamid Baeidinejad has also been threatened with death by a member of the extremist group which carried out the attack on the Islamic Republic's embassy in London.
Iranian Foreign Ministry Spokesman Bahram Qassemi on Thursday chided British leaders over their anti-Iran remarks during the Saudi crown prince's first official foreign visit, calling on them to stop trading global peace and security for economic interests.
Qassemi condemned the "irresponsible unison" of the British and Saudi officials in accusing Iran of destabilizing the region.
