Rwanda's President Paul Kagame speaks to students during a visit to Baruch College in New York May 2, 2007. In an interview with Reuters, Kagame expressed frustration at the four-year-old conflict Sudan's Darfur region and said he was "ringing an alarm bell" for the world by threatening to withdraw Rwanda's 2,000 peacekeepers from the African Union force of some 7,000 troops in Darfur.
