ALGIERS, Algeria (AP) - Algerian protesters are vowing to continue demonstrations until the government falls.
      
Thousands defied a ban on protests today, rallying in the capital to demand democratic reforms. They were met by a massive deployment of riot police, who set up barricades outside the city to stop busloads of demonstrators from joining.
      
A human rights activist says more than 400 people were arrested.

Thousands of people defied a government ban to take to the streets of Algiers. Organizers estimated the crowd at about 10,000, but riot police were also out in massive numbers to disperse crowds. Algerian news reports say security forces outnumbered demonstrators 3-1.
      
Tensions have been high in the sprawling North African nation of 35 million since five days of riots in January over high food prices.
