Obama vows to work with UN for Darfur peace

US President Barack Obama, declaring the violence in Darfur and inaction in the face of its worsening humanitarian crisis are “not acceptable,” pledged today to work more closely with the United Nations to bring peace to western Sudan’s conflict-wracked region.

Mr Obama’s response during a nearly hour-long White House meeting with UN Secretary General Ban Ki-moon significantly ratcheted up the US response to Sudan President Omar al-Bashir’s expulsion of 13 aid groups.
