You may be confusing the words "capital" and "capitol." A "capital" is a city. It's that contains the center of government for a country or a state. It is always the whole city. A "capitol" is a building or group of buildings within the capital city, usually housing the main government offices. Every country has a capital. Not every capital city has a capitol. Whether the national offices are called "the Capitol" is a matter of tradition and history. The name comes from ancient Rome where the center of government was on the Capitoline Hill. I don't know why, but capitol buildings are usually impressive monuments featuring a dome. Within the United States many, but not every state capital has a building called the "Capitol." For example, I live in Massachusetts where the main state government building is simply called "the State House." So Massachusetts has a capital (the city of Boston) but not no Capitol. Below, the capital of Cuba is the city of Havana. The capitol of Cuba is El Capitolio, a building within the city of Havana.

To add on, capital of (word) can be the capital of a country, state or territory. For example, the capital of the USA is Washington DC. The capital of the state of Texas is Austin. The capital of the territory of Puerto Rico is San Juan.

The capital city is correct. Second statement "Capital of " can be used as Capital of Iraq. Example : Baghdad is capital of Iraq.

The image I posted didn't display correctly for some reason. I'm going to try again. The capital city of Cuba is Havana. El Capitolio is the capitol building. It is in the capital city.
