We're following breaking news out of Washington, DC where two Metro subway trains have collided killing at least six people and injuring at least 76 others. One of the dead was the operator of one of the trains.
The accident happened during the evening rush hour on the Red Line in the District of Columbia, near the border with Takoma Park, Maryland. We'll have the latest details on the crash.
We're also following new developments from Iran. There were more protests in Tehran today with riot police and the pro-government Basij milita confronting demonstrators. A vigil was to be held in memory of Neda, a young woman whose death was caught on camera over the weekend. Tonight, we'll have the latest on her murder. See how Neda has become a symbol of the struggle in Iran
And, we'll have raw politics of the uprising. There are calls for Pres. Obama to take action. Do you think he should? Sound off below.
And, in South Carolina the governor has disappeared. Vanished. No one has reportedly spoken with Mark Sanford since Thursday. Not even his wife or children. Not even on Father's Day.
