Katherine Wallace emails a heads-up about a June 9 rally (6:00 PM in Cambridge Common, near Harvard Square) to pressure the UN to help Sufi Muslims who are being persecuted by the Sudanese government. The presence of Kofi Annan, who is speaking at Harvard’s commencement, provides part of the rally’s rationale.
More information is here.
UPDATE: I just realized that I posted a bad link in the above paragraph. My apologies. I fixed the link, which leads to a good source of information about the anti-slavery movement (not just the rally).
