Sudanese officials said Tuesday they are investigating a shooting attack on a vehicle carrying at least one diplomat in the country's capital. An Arab television station said the attack had targeted a US diplomatic car, but US officials would not immediately comment or confirm that. The Sudanese officials, speaking on condition of anonymity, said it was unclear if the car was a US or United Nations vehicle. But Al-Arabiya television said the attack had occurred on a US vehicle, and said a Sudanese driver was killed and an American wounded in the attack. The US Embassy in Khartoum had no immediate comment on the incident. Likewise, there was no immediate comment from State Department headquarters in Washington. It was unclear if the attack was targeted, or a random crime. Crime is fairly high in Khartoum, Sudan's capital, although much lower than in other east African cities like Nairobi, Kenya.
