Hundreds of Algerians took to the streets of the capital on Friday to demand President Abdelaziz Bouteflika quit immediately, as mass protests against the veteran leader entered a fourth week. Protesters gathered in the city centre defying rain, carrying Algerian flags and pamphlets. "Rain will not stop us from continuing our pressure," said 23-year old Ahmed Khoudja. Bouteflika, who has ruled for 20 years, bowed to the protesters last week by reversing plans to stand for a fifth term. But he has stopped short of stepping down and said he would stay in office until a new constitution is adopted, effectively extending his present term.
