This is the OCFTC Number 5, from Nahr El Mott to Bhaness.
Don’t confuse it with the other Number 5, that goes from Hamra to Ain Saadeh.
Both 5s go to Ain Saadeh via Fanar, but each takes a different route through town: the OCFCT Number 5 via the Lebanese University (Fanar Campus) road, and the private Number 5 via ‘7ay al-Arman‘.
