UK's William Hague says 'circumstances are right' to re-open embassy in Iran as relations thaw

British Foreign Secretary William Hague says "circumstances are right" to reopen Britain's closed embassy in Iran.

He told Parliament Tuesday he is satisfied that British embassy personnel in Iran would be safe in Tehran and would be allowed to work without hindrance.

"Iran is an important country in a volatile region, and maintaining embassies around the world, even under difficult conditions, is a central pillar of the UK's global diplomatic approach," he told Parliament in a written statement.

The British Embassy in Tehran was closed in late 2011 after hard-liners overran the building.

The two countries have been in contact in recent days because of shared concerns over mounting violence in Iraq.

American officials have also expanded contacts with Iran recently.

Details about timing have not been announced.
