Libya shares land borders with six countries:
It also has a Mediterranean coastline (north).
The original answer stated “Sudan does not share a border” but then listed Sudan as a bordering country—a contradiction. Sudan does border Libya (271 km in the southeast desert).
Examples: Morocco, Mali, Chad? No, Chad does. Niger? Yes. So any country not in the list above (e.g., Morocco, Mauritania, Israel, Greece, Italy, Malta) does not border Libya.
If this was a multiple-choice question, the correct answer depends on the options given—but Sudan is not the correct choice for “does not border.”
