Iran’s opposition prepared to defy authorities and take to the streets Thursday for another day of massive protests against the disputed re-election of President Mahmoud Ahmadinejad.
In a posting on his Web site, defeated opposition candidate Mir Hossein Mousavi called on his supporters to wear black and gather for street marches to mourn those killed in post-election violence.
Iran has confirmed that at least seven protesters have been killed in clashes with a pro-government militia since Monday.

Official results show incumbent President Ahmadinejad won Friday’s election by a huge margin. Opposition allegations that the vote was rigged have triggered Iran’s most serious unrest since the 1979 Islamic revolution.
A spokesman for Iran’s powerful Guardian Council, made of clerics and Islamic law experts, told state media Thursday the legislative body has begun investigating a total of 646 complaints of irregularities in the June 12 vote. The council has also invited Mr. Mousavi and two other defeated candidates to a meeting Saturday, to discuss their concerns about the election.
