More than 20,000 anti-government protesters gathered in the Yemeni capital, Sanaa, for a "day of rage" against President Ali Abdullah Saleh.
The demonstrators called for a change in government and rejected Mr Saleh's offer to step down in 2013 after more than 30 years in power.
Meanwhile, a similar number of his supporters rallied in a central square.
