Yemeni police hold 'demo leader'
Yemeni police arrested a woman activist for leading anti-government protests, setting off a second day of street demonstrations.
Police used tear gas and batons to disperse hundreds of students, activists and politicians who demonstrated in the capital Sanaa to demand the release of Tawakul Abdel-Salam Karman, who was arrested early on Sunday.
Interior minister Mouthar al-Masri told state television that people had the right to express their views but demonstrations, gatherings and marches should be staged within the boundaries of the law.
Ms Karman is a senior member of the opposition Islamic fundamentalist Islah Party.
