In Yemen, pressure is growing on President Ali Abdullah Saleh to resign after the leaders of two of Yemen's most important tribes abandoned the president and joined the anti-regime movement. Reports say, powerful tribal leaders, including those of the Hashid and Baqil, pledged to join protests against Saleh at a gathering north of the capital. President Saleh has already ordered the formation of a government committee to open a dialogue with protesters. Protestors are demonstrating in the country asking President Saleh to step down who is in power for more than 32 years.
