"Michelle and I know several members of Emanuel A. M. E. Church, we knew their pastor, who, along with others, gathered in prayer fellowship and was murdered last night.

Police have described the attack as "a hate crime". From Washington, Babara Pilette reports.

"State police have launched a massive hunt for the gunman backed up by federal reinforcements. The suspect is said to have joined a prayer meeting at a historic black church in Charlestons last night. According to police, he sat there for an hour before standing up and opening fire on the congregation, killing nine people, including a state senator. The senator's cousin told local media that the gunman reloaded five times during the attack and made racist comments about his victims."

And today we're going to be presenting the Greek government's ideas along those lines, the purpose is to replace costly discord with effective consensus."
