Yemen.

Population - Who is to say.
Location - Near Saudi Arabia.
Known for - Muslims.

Yemen is located right next to Saudi Arabia, on the Gulf of Aden. It has a tourism website entreating potential tourists to come and visit Yemen.

The website says Yemen's natural beauty, culture and cities are all reasons to visit Yemen.

Yemen is a fucking dirt pit populated by crazy Jihadists, ninjas and sandy, sandy bastards.

There are sixteen or something million people, half of them under fifteen. There are also an estimated eighty million weapons.

It is one of the world's poorest countries due to it's main export being terrorists.

The only reason I could think of for people going to Yemen is to visit an al-Qaeda affiliated training camp.
