Egypt's foreign minister Mohamed Kamel Amr, vowing not to give up "a single drop of water from the Nile," said June 16 he will go to Addis Ababa to discuss a giant dam that Ethiopia has started building in defiance of Cairo's objections. "No Nile—no Egypt," he said at a press conference. Last week, Ethiopia summoned the Egyptian ambassador after politicians in Cairo were shown on TV calling for military action or supporting Ethiopian rebels. Ethiopia says the $4.7 billion Great Ethiopian Renaissance Dam on the Blue Nile will eventually provide 6,000 megawatts of power. Egypt was apparently caught by surprise when Ethiopia started diverting the Blue Nile to begin construction last month.

At least 163 were reported dead March 28 in clashes at Okello, in Pibor county of South Sudan's Jonglei state, pitting government troops against a rebel force whose commander David Yau Yau is said to be among the slain. (See map.) South Sudan accuses Khartoum of supporting the rebels, with military spokesman Col. Philip Aguer saying a seized airstrip was used for arms drops. He suggested Sudan is arming the rebellion in a bid to block the South's plans to build an oil pipeline through Ethiopia to a port in Djibouti. Aguer said the South's military, the SPLA, would continue to "deal with the militia group." (The Guardian, March 28) A Kenyan route for the pipeline has also been broached, with the aim of freeing the South from having to export oil through Khartoum's territory.

Six people were injured Dec. 9 as Sudanese police used tear-gas against hundreds of student protesters near the University of Khartoum. The protesters—who chanted the iconic Arab Spring slogan "The people want to overthrow the regime"—were marching to demand justice in the case of four students from the Darfur region who were found drowned in a canal near the campus of Gezira University, south of the capital, on Dec. 7, after they had participated in protests against tuition hikes. The Khartoum protesters marched through the city center, chanting "Killing a student is killing a nation."

South Sudan and Sudan announced Aug. 4 they have reached a deal over the south's use of Khartoum's oil pipelines and distribution of oil revenues—potentially ending a dispute that prompted South Sudan to shut down its oil production in January and nearly led to war. Under the deal reached at talks in Addis Ababa, South Sudan will pay $9.48 per barrel to use one of Sudan's pipelines to export crude, and $11 to use a second leading to a refinery before reaching a sea terminal. Khartoum had originally demanded $36 per barrel.
