Pakistan President Pervez Musharraf has ordered security forces to take firm action against rioters following the assassination of opposition leader Benazir Bhutto. The violence has left at least 44 people dead and dozens injured. Mr. Musharraf insisted the measures were to protect people. VOA's Ayaz Gul reports from Islamabad that a bitter dispute has also erupted over how the 54-year-old politician died and who was behind her assassination.
