Lebanon civil war: From rival fighters to side-by-side bikers
Marwan and Elie fought for rival militias in Lebanon's civil war, which divided Beirut into two isolated districts - east and west.
However, their common passion for motorcycles unified them and they have become close friends and side-by-side riders.
They have been joined by many other ex-fighters, who now organise trips and ride together through Lebanon.
