The hearings, which began last Friday, are being conducted in secret by the military as it tries to determine whether 14 alleged terrorist leaders should be declared "enemy combatants" who can be held indefinitely and prosecuted by military tribunals.

Hearings for six of the 14 have already been held. The military is not allowing reporters to attend the sessions and is limiting the information it provides about them, arguing that it wants to prevent sensitive information from being disclosed.
