It is likely that you meant the "Zagros Mountains" not the (non-existent) "Zagreb Mountains". (Zagreb is the capital of Croatia.) The Zagros Mountains have served as an imposing physical barrier on Iran's western edge, preventing numerous invasions of the territory from the Iraqi side, most recently in the Iran-Iraq War of 1980-1988.
Those would be the Zagros Mountains, which run along Iran's western border.

The Elburz Mountains which extend along the northern part of Iran and the Zagros Mountains which extend along the western part of Iran. ;) I know this because we are studying the Middle East in Geography now.

The Zagros Mountains are the main mountain range in Iran. The mountains bisect the country from the northwest to the southeast. Along the Caspian Sea littoral is the narrow but quite high Alborz Mountains.
