At least 'nine protesters shot dead' in Yemen   Yemeni security
forces have opened fire on protesters in the capital, Sanaa,
killing at least nine people, witnesses and doctors say. They
say about 100 people were also injured in the shooting.  It
comes a day after the government and opposition agreed to sign a
deal soon under which President Ali Abdullah Saleh would step
down within 30 days.  But many people across Yemen are angry the
president will get immunity under the agreement, correspondents
say.  The BBC's Richard Forrest reports.
