Song in PA TV documentary calls for attacking Israel, "the snake's head"

Visuals of Palestinian terrorists in training are shown while the following song is played:
Egyptian song writer Sheikh Imam in PLO documentary "For The Roots Shall Never Die," broadcast on PA TV:
"Oh Palestinians, the revolution is certain,
With the rifle we will impose our new life...
Oh Palestinians, [the Zionists] shot you with a rifle
The Zionists kill your doves at the holy sites.
Oh Palestinians, I want to go and be with you
With fire in my hands, and together with you
my hand will strike the snake's head [Israel]."
