Adnauseam's travel advisory.
Travellers and tourists are advised to be cautious in their choice of a destination in Africa. See the link below (which I'll comment on), and I've added a few because they have been left out . Avoid the following places if you want to travel in Africa. As per link:
Liberia--putting itself together under Mrs Leaf. Could be safe in future.
Guinea--very unstable at the moment. Demonstrations against government. Nothing for tourists here.
Kenya--Lovely destination. Crime the big problem in the cities esp. Nairobi.
Burundi--Crime levels high. Rebel attacks against capital, Bujumbura.
Nigeria--Do not go near Port Harcourt. Crime is excessive in Lagos.
Algeria-Nice tourist destination (Mediterranean coast especially). Terror attacks lately. Caution needed.
Central African Republic--Tensions high in this country. Rebel forces. Best avoided.
DRC--Stabilising after elections but many areas unsafe. Dangerous conditions for residents and visitors.
Cote D'Ivoire (Ivory Coast): Tensions high. Security situation remains tense and potentially volatile.
Sudan-Khartoum relatively safe. Anywhere outside is a no-no. If you work for UN stay away.
Eritrea-Asmara relatively safe. Tensions due to conflict with Ethiopia.
Somalia--A big red NO. Most unstable country in Africa. Avoid at all costs.
Chad-Due to clashes along borders with Sudan, non-essential travel not advised.
And a few more that I have added, not because the State Department is out of date, but rather because I know this continent well.
Republic Of South Africa: Tourist haven but serious crime and muggings prevalent in cities. Caution at all times especially at night and take care with belongings.
Lesotho--avoid during present elections. Beautiful tourist destination. Tourists advised to stay over border.
Zimbabwe--Tourists welcome but shortage of basic foodstuffs and over-eager policing.
Equatorial Guinea--unstable nation not suited to tourism.
Sierra Leone--still unstable--not suited to tourism.
Sheesh, Africa sounds like a really dangerous place. Don't worry,there are many great countries to visit!
