Nearly 20,000 protesters across Yemen today went to the streets to celebrate the Egyptian revolution and called for uprising against their President Ali Abdullah Saleh.In capital Sanaa, more than 5,000 protesters, including students, journalists and human rights activists, gathered outside University and marched along the main streets waving Egyptian flags and calling for the Egyptian-style uprising against President Saleh.Forcing their way to Sana's main square Al-Tahrir, protesters shouted, they will oust President Saleh. In the southern port city of Aden, thousands of protesters also marched along the streets to celebrate the Egyptian revolution. Protesters clashed with soldiers who fired in the air to disperse the march.Witnesses said one was killed, but security forces arrested many protesters. Saleh, who has been in power for more than 30 years, announced earlier this month that he will not stay in office or pass power to his son when his term expires in 2013.In Algeria too, thousands of people defied an official ban on demonstrations in the capital and gathered in the city centre for a pro-reform protest today. The move comes the day after weeks of mass protests in Egypt succeeded in toppling the president.Organisers of the march estimated some 10,000 people had flooded downtown Algiers, where they skirmished with riot police attempting to block off streets and disperse the crowd. Some arrests were reported.Protesters chanted slogans including “No to the police state” and “Bouteflika out,” a reference to President Abdelaziz Bouteflika, who has been in power since 1999.Under the country's long-standing state of emergency, protests are banned in Algiers, but the government's repeated warnings for people to stay out of the streets apparently fell on deaf ears.The march comes at a sensitive time in Algeria just a day after the uprising in Egypt that forced Hosni Mubarak to abandon the presidency after 30 years. It also comes on the heels of a “people's revolution” in neighbouring Tunisia that pushed President Zine El Abidine Ben Ali into exile on January 14.The success of those uprisings looked bound to fuel the hopes of those seeking change in Algeria, though many in this conflict-scarred country fear any prospect of violence following the brutal insurgency by Islamist extremists in the 1990s that has left an estimated 200,000 dead.Organised by the Coordination for Democratic Change in Algeria, an umbrella group of human rights activists, unionists, lawyers and others, today's march was aimed at pressing for reforms to push Algeria toward democracy and didn't include any specific call by organisers to oust Bouteflika.
