The FBI has said it is considering whether to launch an investigation into an alleged incident on an aircraft carrying Brad Pitt and his children, when he reportedly got into an argument with 15-year-old son Maddox.

Angelina Jolie filed for divorce from the actor on Monday, citing irreconcilable differences, and has asked for physical custody of the couple's six children.

In a statement, the FBI confirmed it was aware of allegations involving an "aircraft carrying Mr. Brad Pitt and his children".

"The FBI is continuing to gather facts and will evaluate whether an investigation at the federal level will be pursued," it added.
