Eloquent where clause based on other tables

One of my Laravel models is called Property, which contains all the Real Estate properties within my application. Each Property contains a city and country.

Therefor I have the following relational tables:

City_property (holds city of properties)

| id | city_id | property_id |
|----|---------|-------------|
| x  | 2       | 1           |

City_country (holds country of city)

| id | country_id | city_id |
|----|------------|---------|
| x  | 3          | 2       |

So when fetching all my Properties, I want to where clause on the Country of the properties, so I'm able to only fetch Properties where country = 5 (for example).
