After gathering outside the presidential palace, the marchers headed to the UN offices shouting "Allah o Akhbar (God Is Great) and waving banners in English and Arabic proclaiming "Darfur Is the Graveyard of US" and "No to Foreign Intervention."

Many of the marchers were wearing students' uniforms, green for the boys and blue for the girls, who were all wearing headscarves.

One contingent of youths were wearing black shirts and red headbands marked "Martyrs Brigades."

The protest was organized by an umbrella grouping of several political parties called the Association of Faith and the Motherland.

The UN Security Council passed a resolution last Friday giving Khartoum 30 days to disarm the pro-government Arab Janjaweed militia accused of committing atrocities against black civilians in Darfur.
