Lebanese President Michel Aoun tripped and fell face down as Arab heads of state gathered at the start of their summit at the Dead Sea in Jordan on Wednesday, television footage showed.
Aoun, 82, appeared to trip on a low, red-carpeted podium where flags of Arab states had been arranged.
Aoun became head of state last year in a political deal that saw Saad al-Hariri appointed prime minister, ending a 2-1/2 year vacuum in the presidency.
