The country is called Somalia
The people are called Somalis (singular - Somali)
English spelling of the capital is Mogadishu.
We refer to "The United Nations".
We "plead with" someone to do something.
I don't really know what you mean by "the migration of". People migrate from one country to another. Usually, people are not "migrated" by another country. Do you mean that Saudi Arabia is forcing Somalis to move around Somalia, or even to move to Saudi Arabia?
