Tucker Carlson's Brother Buckely Calls Sydney Massacre an 'Op', Mocks Wounded Lawyer Arsen Ostrovsky

Among the victims were 10-year-old Matilda, the youngest killed, and an elderly Holocaust survivor, highlighting the targeted nature of the violence against Sydney's Jewish community. Australian authorities have confirmed the attack, carried out by father-and-son gunmen Sajid and Naveed Akram, as an act of antisemitic terrorism.

Livingstone's post directly questioned whether Tucker Carlson would condemn his brother's alleged statements or if he endorses them, calling the behavior "inhumane and disgusting."

Buckley Carlson, a Republican political operative and former communications staffer, is known to maintain a low public profile.

But for some reason, he ventured into very dangerous territory, when he should have either said nothing, or expressed condolences. But to mock someone whose head is covered in blood after being shot at, at an actual terror attack? That's a new kind of low.

The post has not been removed, and X has confirmed that he was its author.

Tucker Carlson has not responded publicly to the allegations.

The claims come amid heightened global sensitivity to antisemitism following the Bondi tragedy, with community leaders and officials urging unity against hate and misinformation.
