Iranian opposition leader Mir Hossein Mousavi, who has been under house arrest for over three years, has begun medical treatments following a two-week delay.

Mousavi’s daughters reportedly told the opposition website Kaleme, in a report published on Thursday, that they met with their parents on May 14 and were told that the authorities have allowed doctors to proceed with Mousavi’s heart treatments.

Mousavi was taken to hospital about three weeks ago for heart complications, but on the same day security forces returned him to his home, where he is being held under house arrest. Mousavi’s children then began to protest, reporting that that the government was denying their father badly needed medical care.

Kaleme also published a report from one of the opposition leader’s physicians, who confirmed that Mousavi’s treatments were urgently needed and had to be done right away.

Mousavi’s daughters began meeting with a number of religious leaders in Qom, describing their father’s situation and seeking the clerics’ support.

Mousavi and his wife, Zahra Rahnavard, have been under house arrest since February 2011 for challenging the legitimacy of the 2009 presidential election outcome.
