"He bravely fought to the very end on the battlefield," he added.
"His fate – beautifully pictured in his last image – is not a deterrent but a source of inspiration for resistance fighters across the region, Palestinian and non-Palestinian," he stated.
"We, and countless others around the world, salute his selfless struggle for liberation of the Palestinian people," Araghchi noted.
"Martyrs live forever, and the cause for liberation of Palestine from occupation is more alive than ever," he stressed.
