American terror suspect Jose Padilla has pleaded not guilty to charges he conspired to murder U.S. nationals and provide material support to terrorists.
After making his plea in a civilian court Thursday in Miami, Florida, Padilla was denied bail.
Padilla has already been held for more than three years by the military on suspicion he planned to explode a radioactive "dirty" bomb in the United States. His status as what the White House calls an "enemy combatant" - someone who can be held indefinitely without charge, has been the subject of several court rulings. Human rights groups oppose the enemy combatant designation and its consequences.
Padilla's case was transferred to civilian court last week at the urging of the Bush administration. The current charges against him make no mention of the dirty bomb plot.
