Ozzy Osbourne has expressed his shock at the death of guitarist "Dimebag" Darrell Abbott, who was shot during a concert.

Former Pantera star Abbott was one of five people killed in Ohio as his band Damageplan took to the stage.

Black Sabbath frontman Osbourne, who often toured with the 38-year-old, said: "I'm absolutely beside myself with grief. I can't for the life of me understand why someone would do this."

Abbott and three others were shot when a man stormed the stage at the Alrosa Villa Club in Columbus and began firing at the band and crowd.

Nathan Gale, 25, was then shot and killed by a police officer who arrived shortly after the first shots were fired reports BBC online.

The other men killed were named as club employee Erin Halk, 29, fan Nathan Bray, 23, and Jeff Thompson, 40, who was affiliated with the band.

Two other people were taken to hospital following the incident but their condition is unknown.

No motive has yet been established for the rampage, although Sgt Brent Mull said witnesses had described hearing Gale accuse Abbott of being behind the split of the Grammy-nominated heavy metal band Pantera.
