SYDNEY, Australia — The Australian Federal Police raided the Sydney offices of Australia’s public broadcaster on Wednesday, apparently in connection with an article published in 2017 about Australian special forces being investigated over possible war crimes in Afghanistan.

The raid of the Australian Broadcasting Corporation’s offices came a day after the same agency searched the home, computer and cellphone of a journalist who reported on secret correspondence between government ministries over a plan to expand intelligence agencies’ surveillance powers. The police said the two raids were not related.

John Lyons, the executive editor of ABC News and the head of its investigative journalism unit, said on Twitter that the police had arrived at ABC’s headquarters with a search warrant that named three journalists. “We’ll be taking material with us. It will be sealed,” he quoted one of the officers as saying.
