Hezbollah Secretary-General Hassan Nasrallah extolled the rights of Palestinians to return to their land in Israel and said he believes it will happen soon, the Lebanese Naharnet reported.
Meanwhile Palestinian citizens of Lebanon declared a day of mourning Monday for the 10 people killed on the border with Israel on 'Nakba Day'.
"We must praise the courage and faith of all those who protested yesterday on the Lebanese and Syrian borders with occupied Palestine as well as within Palestine, those who stood with bared chests and heads high before the tyranny of the enemy army," the website quotes him as saying.
On Sunday 'Nakba Day' protests on Israel's borders turned violent as dozens of Syrian civilians stormed the border fence and infiltrated Israeli territory. In Lebanon protesters attempted the same but were fired upon by the Lebanese army.
"Dozens died as martyrs and hundreds were injured – they yelled loudly of the pure blood so that the world would hear their determined stance."
Nasrallah said the Palestinians living in Syria and Lebanon would not settle for "an alternate homeland" and that they would "dedicate all blood, souls, and physical sacrifice" to return to their lands.
"Your message was that you are determined to liberate the land, be the sacrifices precious as they are, and that the fate of (Israel) is to disappear, and no initiative, deal, or border will protect it. Your message is that your return to Palestine is a right closer to being realized now than at any time in the past," he said.
"We stand beside you, rejoice in your joy and wallow in your pain. We will march together in the path of the resistance in order to complete the victory, and free all of our lands and holy places."
Fatah in Lebanon, meanwhile, declared a day of mourning and a general strike in honor of those who died on Israel's border Sunday.
Mounir Maqdah, Fatah commander in southern Lebanon, said funerals will be held in al-Bass, Burj al-Chemali, Miyeh Miyeh and Ain Hilweh refugee camps.
