I don't have anything noteworthy to add about the 9/11 commemorations going on today. Instead, I'd like to bring your attention to some riots that are currently going on in Kampala.
Apparently, the President is not allowing the Kabaka, the traditional king of the Buganda people, to visit an area in Kampala, saying there is no way he can guarantee his safety. This has led to riots which have killed reportedly 10 people by this time. The police have been using live rounds as well as tear gas to disperse crowds. The latest I hear is that the military have started directing several news channels and editing their reporting.
