Two Iranian doctors imprisoned for allegedly plotting to overthrow the government have been awarded a global health prize.
Kamiar and Arash Alaei were arrested in June 2008 and accused of communicating with the US to unseat the regime of Iranian President Mahmoud Ahmadinejad.
One of the two brothers, released earlier this year, was able to accept the award in Washington.
Kamiar Alaeia, 37, said they had never been involved in politics.
He told the BBC World Service that a project they began in a small clinic was so successful it was replicated nationwide and in the neighbouring countries of Afghanistan and Tajikistan.
