What capital city with ten letters?

Some capitals I can think of:

Paramaribo (capital of Suriname)
Mexico City (capital of Mexico)
Bridgetown (capital of Barbados)
Copenhagen (capital of Denmark)
Wellington (capital of New Zealand)
Nouakchott (capital of Mauritania)
Kuwait City (capital of Kuwait)
Bratislava (capital of Slovakia)
Georgetown (capital of Guyana)
Luxembourg (capital of Luxembourg)
Addis Ababa (capital of Ethiopia)
Libreville (capital of Gabon)
Montevideo (capital of Uruguay)
Panama City (capital of Panama)
Basseterre (capital of St. Kitts and Nevis)

Mind you that I didn't count spaces (like in Addis Ababa), just the letters.
