In Iraq, sectarian violence between Sunni and Shia ethnic groups is spiking once again.
Journalist Sahar Issa lives in Baghdad.
She tells anchor Marco Werman that the hours after prayers on Friday are an especially fearful time in the capital.
"Every Friday has been a 'terror Friday,'" Issa says. "We just don't know what is going to happen. Sunni enclaves become like camps, deployment of Army, deployment of Special Forces, deployment of all military kinds."
