Lawyers for ​relatives of 9/11 victims butted heads on Thursday with lawyers for Saudi Arabia over efforts by the ​families to seek documents from the Saudi equivalent of the CIA.

“It’s a significant affront to a foreign government,” lawyer Michael Kellogg said of the request for information from Saudia Arabia’s General Intelligence Directorate, or GID.

“Certainly the CIA would not answer such a question.”

Kellogg complained to Manhattan federal ​Judge Sarah Netburn.

Kellogg made the remarks after lawyers for hundreds of families of 9​​/11 victims and survivors requested that the lawyers representing Saudi Arabia obtain files from the Saudi intelligence agency in addition to five Saudi-run agencies that have already been approved for discovery in the civil matter.

Lawyers for the 9/11 families made the request in an effort to prove that Omar al-Bayoumi, who helped set up some of the attackers in San Diego, was a Saudi intelligence official.

Judge Netburn ordered that the Saudis first turn over documents from five agencies already identified as having documents relevant to the case. If any of those documents indicate the Saudi equivalent of the CIA also has something to offer, she will revisit the issue, she said.

In March, a Manhattan federal judge rejected Saudi Arabia’s motion to throw out lawsuits claiming the Middle Eastern nation helped plan the 9/11 terror attacks– paving the way for evidence collection in the matter.
