Two neighboring countries in northern Africa, whose capitals have the same name with the names of the countries?

Algeria has the largest territory of all African countries. However, most of its area is covered by the Sahara Desert. In the north, this country has a long coastline in the Mediterranean. The capital of this country is also called Algeria. In the northeast, Algeria is adjacent to Tunisia, which has a much smaller area. In this country, the name of the capital also coincides with the name of the country. On the territory of Tunisia, many ancient buildings have been preserved from the era of Carthage and Rome, as well as the times of the Arab conquest.
