The World Food Programme says a small convoy of humanitarian aid trucks has entered Sudan, offering a slight respite to thousands of displaced people facing famine in western Darfur’s Kereinik region. The U.N. convoy comes after the Sudanese military agreed to reopen portions of Sudan’s border with Chad. The Sudanese army had previously allowed only a trickle of aid into Sudan, claiming the rival Rapid Support Forces were using the routes for smuggling weapons.
