DUBAI - A senior British diplomat made a brief visit to Tehran on Monday for talks with officials on the strained ties between the two countries and on Iran's nuclear program, Iran's official IRNA news agency reported.
Earlier, IRNA said Tehran and London were looking to restore full diplomatic ties, all but severed after a 2011 raid on Britain's embassy in the Iranian capital.
Simon Gass is the most senior British diplomat to visit since the raid, which came after Iranian allegations that Britain had masterminded mass protests that followed then-President Mahmoud Ahmadinejad's disputed re-election in 2009. Britain has flatly denied the accusations.
"There is the likelihood of a rise in the level of diplomatic ties between Tehran and London," IRNA quoted foreign ministry official Majid Takht-Ravanchi as saying.
Gass is also London's representative in six-power nuclear talks with Tehran, and met senior members of Iran's nuclear negotiation team, IRNA said.
