A small group of anti-Israel activists briefly took over the roof of Australia’s parliament building Thursday morning in a move condemned by the country’s prime minister as “reckless.”

“Peaceful protest has an important place in our society but this was not a peaceful protest,” Anthony Albanese told Parliament during question time following the episode, which lasted about 90 minutes.

“These actions have done absolutely nothing to advance any cause, indeed they have hurt the cause that those engaged in this reckless activity believe they are advancing,” he said.
