SANAA (AFP) - Tens of thousands of Yemenis marched through the country's second city Taez on Sunday in what they called a "day of rage" against President Ali Abdallah Saleh on the anniversary of his rise to power in 1978. Demonstrators assembled on Taez's main arterial road, chanting anti-Saleh slogans and waving black flags to mourn the embattled president's 33-year rule, the rally's organisers said. Meanwhile, Four soldiers and 10 militants linked to Al-Qaeda have been killed in clashes in the southern Yemeni town of Zinjibar, a military source said on Sunday. The fighting since Saturday evening centred around the base of the 25th Mechanised Brigade, near which troops found and destroyed an arms cache belonging to elements linked to Al-Qaeda, the source added. Protesters called for the resignation of Saleh, who has been in Saudi Arabia for the past six weeks receiving treatment for wounds sustained in a June 3 bomb blast at his presidential compound in Sanaa.
