WAGE RAGE: Demands for higher wages spread to at least two other mines, raising fears of further protests at more South African mines that provide most of the world's platinum.

PRESIDENT'S PROBLEM: President Jacob Zuma told striking miners the nation's leaders mourn with them, but he refused their request to visit the site where police killed 34 strikers and wounded 78.

MONEY PIT: Striking miners want a monthly minimum wage of R12,500 ($1,560). The current minimum is R5,500. Platinum mines hit by low world prices and flagging demand may not be able to meet the demands, industry analysts say.
