Sanaa (ANTARA News/Reuters) - Yemeni forces opened fire on a crowd of tens of thousands of protesters demonstrating on Wednesday in the capital Sanaa to unseat the president, killing at least one demonstrator and wounding scores, witnesses said.

In the industrial centre Taiz, snipers killed two protesters and dozens were injured by gunfire, tear gas and bat-wielding plainclothes security men. Protesters retaliated by torching a police building and sealing off government buildings.

The bloodshed is likely to add to public rage ahead of Friday, traditionally the main day of unrest during a three-month-old revolt against President Ali Abduallah Saleh inspired by uprisings across the Arab world.

Crowds have lost patience with stalled negotiations to end Saleh`s 33-year rule, and violence is surging in a country where half the population owns a gun. Wednesday`s march in Sanaa saw protesters attempt to reach the cabinet building.

"This is a massacre, they are opening fire randomly," Mohammed al-Qibly, a leader of a youth protest movement in Sanaa, said on Al Jazeera television. "The scene is terrifying in every sense of the word."

A doctor at the scene told Reuters one person was killed. Witnesses said some 40 people were shot and protesters stopped to help treat the wounded, who were rushed away in private vehicles as the gunfire continued.

"Forces opened fire heavily when protesters got around 200 metres away from the cabinet, but the protesters didn`t back away at first," Yemeni journalist Abdulsattar Mohammed said. "A number of injured fell and they were carried away to hospital on motorcycles when police stopped ambulances from entering."

Neighbouring oil giant Saudi Arabia and the United States fear escalating violence could push impoverished Yemen, already riven by tribal and separatist conflict, into chaos that could allow al Qaeda`s Yemen-based wing to operate freely.

Demonstrators have sought to shut down some of Yemen`s major cities and many have called for a daily general strike.

In Taiz, security forces have shot dead six protesters in three days of clashes. Authorities were struggling unsuccessfully to break up a protest blockade on the education ministry, part of a siege of state buildings that has effectively brought Yemen`s main industrial centre to a halt. (*)
