Sudanese authorities are expressing their regret over Tuesday's deadly shooting of a U.S. diplomat in the capital of Khartoum.
The United States Agency for International Development says 33-year-old John Granville died in the hospital several hours after being shot five times. His driver, 40-year-old Sudanese national Abdel Rahman Abbas, died instantly.
Sudan's foreign ministry says it will continue investigating until an arrest is made in the case. It says the shooting was an isolated incident with no political connotations. Sudanese media reports quote a government official as saying there is no evidence the attack was an act of terrorism.
U.S.-Sudanese relations have been tense because of the violence in Sudan's Darfur region. The shooting happened one day after a joint United Nations-African Union force took over peacekeeping duties in Darfur.
On Monday, President Bush signed legislation allowing U.S. state and local governments to divest from Sudan because of the Darfur situation.
