In Sudan, at least 12 African Union soldiers were killed in Darfur on Sunday in the worst attacks on international troops since they were deployed in 2004. The killings occurred when over a thousand armed rebels stormed an African Union base. More than 50 other troops are reportedly missing. The attack took place just as a new diplomatic initiative for peace got underway. A delegation of so-called “elders” including South African Archbishop Desmond Tutu arrived in Khartoum on Sunday.
