Dzhokhar Tsarnaev's Attorneys To Challenge Prison Conditions

Boston Marathon bombing suspect

(Reuters) - Attorneys for accused Boston Marathon bomber Dzhokhar Tsarnaev are due in court on Tuesday to argue against the restrictive terms of his confinement, which they say are impeding their ability to mount an effective defense.

The 20-year-old defendant is being kept separate from other prisoners at the facility west of Boston where he is being held awaiting trial and his lawyers have been ordered not to share messages from Tsarnaev with the outside world.
