At least 15,000 mostly indigenous anti-government protesters marched Wednesday to the area of Ecuador's capital that is home to the Carondelet presidential palace, which is being heavily guarded to deter potential attempts to breach the premises.

Efe observed that the protesters, who had begun their march at the entrance to Quito's historic center, were advancing peacefully and shouting slogans such as "el pueblo unido, jamas sera vencido" (the people united will never be defeated).

The demonstrators were expected to arrive at Plaza de Santo Domingo and take part in a ritual to commemorate Inti Raymi (Festival of the Sun in the Kichwa language), one of the main festivals on the Andean agricultural calendar.

Separately, another group of demonstrators marched along several streets of north-central Quito and in the financial district on the 10th day of the protests, which were organized by the Confederation of Indigenous Nationalities of Ecuador (Conaie), that South American country's largest indigenous organization.

Both men and women could be seen marching Wednesday in Quito, many of them carrying Ecuadorian flags and making loud noises with vuvuzelas (plastic horns made famous by South African soccer fans).
