Sana'a: Tens of thousands of Yemenis have taken to the streets in the country's capital, calling for President Ali Abdullah Saleh's ouster.

The protests are taking place at four different locations across Sana'a, led by opposition members and youth activists. The crowds are chanting for an end to the government of Saleh, who has been in power for nearly 32 years.

The rally is inspired by Tunisia's popular revolt that topped that country's ruler and this week's deadly protests that have gripped Egypt.

Impoverished Yemen is grappling with a resurgent Al Qaida, a northern rebellion and a secessionist movement in the south.

Saleh has tried to defuse simmering tensions by denying opponents' claims he plans to install his son as his successor and by raising salaries for the army.
