Australia police raid headquarters of public broadcaster ABC

Australian police have raided the headquarters of the country's public broadcaster ABC.

Police arrived with search warrants naming two journalists and News Director Gaven Morris, the ABC says.

According to the ABC, the raid is over an investigative story into misconduct by Australian forces in Afghanistan.

The raid comes one day after police searched the home of a News Corp journalist over the alleged leak of classified information.

ABC journalists have been tweeting about the events since police arrived in the morning.

According to a statement by the police, no arrests were planned and the warrant was "not linked" to the search on Tuesday and was "in relation to allegations of publishing classified material".

"The search warrant relates to a referral received on 11 July 2017 from the Chief of the Defence Force and the then-Acting Secretary for Defence," the statement says without giving further details.

According to the ABC, the search is about the 2017 investigative series known as The Afghan Files which "revealed allegations of unlawful killings and misconduct by Australian special forces in Afghanistan".
