The passengers were treated for minor injuries before continuing on their travels and other airport operations weren't affected, officials said.

It wasn't clear if the suspect was a traveller and the motive for the attack was unknown, airport duty manager Russell Mackey told the San Francisco Chronicle.

A KTVU-TV reporter who was covering the Golden State Warriors’ homecoming at the airport said a large knife was removed from the scene.

Other details weren't immediately available.
