"Using the term house arrest is not correct. Mr Mousavi and Karroubi, along with their wives, are in their homes."

Family members of the two men have said on their websites that Mousavi, Karroubi and their wives had been transferred to Tehran's Heshmatiyeh jail from their residences in the Iranian capital. The families indicated that no one was at the homes of the two leaders, which they said had been left in the dark, or appeared to be vacant.
