Six people are dead in Tate County, Mississippi, after a series of shootings on Friday, according to reporting from CNN affiliate WMC.

CNN spent time embedded with the Sikorsky Brigade in eastern Ukraine operating from a secret base where they conduct combat missions against Russian forces. CNN's Sam Kiley reports.

The horizon disappears for a moment as the nose of the helicopter rears. There's a faint thump as rockets trailing brown smoke arc ahead. The aircraft banks as if flicked on its side by an outside force.
