BOSTON (AP) — Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev are asking for a third time for a judge to hold a hearing on media leaks they say are jeopardizing Tsarnaev's right to a fair trial.

In a court filing Friday, Tsarnaev's lawyers cite a recent piece in Newsweek magazine containing statements from unnamed law enforcement sources. They say the article "casts the entire Tsarnaev family in an extremely negative light" and "suggests that others were somehow involved."

Judge George O'Toole Jr. has rejected two earlier defense requests for a hearing, but he has instructed prosecutors to warn law enforcement against disclosing information about the case to the media. Prosecutors sent a letter to all law enforcement agencies involved telling them of the judge's concerns.

Tsarnaev's trial is scheduled to begin in January.
