Gunman Kills 5 At US Newspaper Office

A gunman has opened fire at a local newspaper office in Maryland, killing five people and injuring others in what police said was a "targeted attack".

Staff at the Capital Gazette in Annapolis said the attacker, armed with a shotgun and smoke grenades, shot through a glass door into the newsroom.

US media have named a suspect held by police as Jarrod Ramos. He is reported to have unsuccessfully sued the newspaper group in 2012 for defamation.

He is a white male in his late 30s. Police have not confirmed a motive tho.
