Nine people have been killed and seven injured in a shooting at a college in the US state of Oregon, say police.

The gunman, 26, opened fire at Umpqua Community College on Thursday morning and was killed in a police shootout.

There were conflicting reports on casualties but Douglas County Sheriff John Hanlin said 10 dead, including the gunman, was "the best" figure.

A vigil was held in a Roseburg park on Thursday evening

Police have not identified the attacker but un-named officers have told US media his name is Chris Harper Mercer.

Mr Hanlin said he would not confirm the name, adding: "I will not give him the credit he probably sought prior to this horrific and cowardly act."

The killer's motive is not known, although police said they were investigating reports that he had warned of his intentions on social media.
