It wasn’t so much unsportsmanlike conduct as sheer barbarism: On Wednesday, the Saudi Arabian men’s national soccer team refused to observe a moment of silence for the victims of the London Bridge terrorists.

Hosting the World Cup qualifying match was Australia, which lost two nationals in the attack. In their honor, the Socceroos wrapped their arms around each other and stood together in a line . . . while the Saudis kept warming up, earning well-deserved boos from the Adelaide Oval crowd.

A spokesperson for Football Federation Australia says the Saudi team was told of the coming one-minute silence — but refused, citing cultural differences.

Sorry: Respecting your host’s needs, particularly in time of sorrow, is universal to human culture.

And stomping on the sensitivities of the victims of Islamist terror is especially grotesque for the national team of a country that funds so much extremism.

Plus, another Saudi club, Al-Ahli, observed a moment of silence last December for Brazilian players killed in a plane crash.

The Saudi Football Federation’s president issued an apology: The “players did not intend disrespect to the memories of the victims nor to cause upset.” Right.

Anyway, justice was served: Australia beat the Saudis 3-2.
