Tens of thousands of anti-government protesters rallied in Yemen on Saturday, some apparently angered by President Ali Abdullah Saleh's rejection of a resignation proposal.
One demonstration was in the southern city of Taiz, the scene Friday of deadly clashes between security forces and anti-government protesters. Witnesses say at least four people were killed and dozens wounded in Friday's unrest.
Protesters also rallied on Saturday in the port city of Aden.
Meanwhile, Yemen has summoned its ambassador to Qatar. Yemen's state-run SABA news agency announced the decision on Saturday after Qatar's prime minister said Thursday that the six-nation Gulf Cooperation Council hoped to reach a deal with President Saleh that called for him to step down. The news agency says the ambassador was recalled for consultations.
For the past two months, anti-government protesters have been calling for an end to his 32-year rule. President Saleh has offered to resign, but only after new elections are held.
Separately, the French News Agency (AFP) says Yemeni army units shelled a suspected al-Qaida haven in the country's south on Saturday after urging residents to leave the area.
