The U.S. military has canceled a pretrial hearing for suspects in the Sept. 11, 2001 attacks, a military spokesman said on Sunday, in another setback for the government in its efforts to try the five men being held at Guantanamo.

A defense department spokesman said the hearing, originally scheduled for Aug. 24 to Sept. 4, was canceled by the military judge.

"The judge cited issues that remain unresolved with regard to a claimed defense counsel conflict of interest," said Commander Gary Ross.

News of the cancellation was first reported by ABC News.

Defense attorneys for Khalid Sheikh Mohammed and four alleged co-conspirators raised concerns in 2014 that they were being spied on by the Federal Bureau of Investigation. They said that created a conflict of interest between them and their clients.

Judge James Pohl, an Army colonel, ruled in July that no conflict of interest arose for defense attorneys.
