Chavez opponents hold demonstration in Venezuela demanding answers about president's cancer

Hundreds of government opponents in Venezuela have held a demonstration demanding answers about President Hugo Chavez's condition while he remains out of sight in a hospital.

Chavez is undergoing treatment in a military hospital in Caracas more than 10 weeks after his latest cancer surgery.

Opposition leaders at Saturday's demonstration criticized secrecy surrounding Chavez's diagnosis and treatment. They say many Venezuelans want the government to tell the whole truth about the president's condition.

Chavez hasn't spoken publicly since before his Dec. 11 surgery, and during that time has been seen only in several photographs released by the government.

Vice President Nicolas Maduro said Friday night that he and other officials had a lengthy visit with the president at the hospital.
