Biden: No indication Iran attack on UK embassy orchestrated

US Vice President Joe Biden said on Thursday he had seen no indication the attack on the British embassy this week in Tehran was orchestrated by Iranian authorities, but it was another example of why the country was a "pariah".

Biden, wrapping up a three-day visit to mark the end of the US troop presence in Iraq, also played down the risk of Iran exploiting the departure of US troops by year-end. (Reuters)
