TEHRAN - Iran's Foreign Ministry Spokesman Abbas Araqchi said that London should take measures to restore relations with Iran, as it was Britain that has unilaterally severed ties with the Islamic republic, Press TV reported on Monday.

"Taking the initiative to restore ties with London requires a revision of UK's approaches and behavior towards Iran," Araqchi was quoted as saying.

Araqchi's statement came after a recent phone conversation between Iranian Foreign Minister Ali-Akbar Salehi and British Foreign Secretary William Hague in which Hague expressed UK's willingness to work with Iran to improve diplomatic relations.

In Nov 2011, thousands of angry Iranian demonstrators broke into two British embassy's compounds following Iran's decision to downgrade its diplomatic ties with Britain in response to the financial sanctions imposed against Tehran.

Following the incursion into its embassy in Tehran, Britain withdrew its diplomats from Iran, shut down its embassy in Tehran, ordered the immediate closure of the Iranian embassy in London and demanded that all its staff leave Britain.
