The Lebanon-based Hezbollah terrorist organization denounced on Tuesday what it labeled as "the deal of shame" announced by "the savage Trump administration."
In a statement issued in Beirut Tuesday, the Iran-controlled terrorist group described the plan as dangerous, adding that it will have very negative repercussions on the future of the region and its people.

It said the US has capped decades of blind support for Israel, its occupation and aggression against Arabs by trying to eliminate the historical and legitimate rights of the Palestinian people.
"This deal would not have taken place had it not been for the complicity and betrayal of a number of Arab regimes, secretly and publicly involved in this conspiracy," it added, in a reference to Gulf Arab countries.
The statement said the deal announced in Washington Tuesday "confirms that resistance is the only option" to liberate occupied land.
In Iran, an adviser to President Hassan Rouhani dismissed the peace proposal as one of "imposition and sanctions."
"This is a deal between the Zionist regime [Israel] and America. Interaction with Palestinians is not on its agenda. This is not a peace plan but a plan of imposition and sanctions," Hesameddin Ashena tweeted after Trump unveiled details of plan in Washington.
Saudi Arabia, a key Arab country and Iran's main regional rival, said it appreciated the Trump administration's efforts and encouraged the resumption of direct talks between Israel and the Palestinians "under the auspices of the United States."
Egypt, the first Arab country to reach a peace deal with Israel, urged Israelis and Palestinians to carefully study the plan.
Jordan, the only other Arab country officially at peace with Israel, said on Tuesday that the only path to a comprehensive and lasting Middle East peace was the establishment of an independent Palestinian state based on pre-1967 borders, and with east Jerusalem as its capital.
"Jordan supports every genuine effort aimed at achieving just and comprehensive peace that people will accept," Jordanian Foreign Minister Ayman Safadi said in a statement issued after US President Donald Trump announced his administration's peace plan.
Safadi called for serious and direct negotiations that solve all final status issues, including protecting Jordan's interests, and warned against the "dangerous consequences of unilateral Israeli measures ... that aim to impose new realities on the ground."
Turkey strongly rejected the US plan, describing it as "an annexation plan aiming to destroy the two-state solution and seize Palestinian territories."
A Turkish Foreign Ministry statement also rejected US President Donald Trump's declaration to keep Jerusalem as Israel's undivided capital, saying "Jerusalem is our red line."
"The United States' so-call peace plan was still-born," the ministry said. "The people and land of Palestine cannot be bought off."
The ministry statement said: "We will not support any plan that does not have the support of Palestine. There will not be any peace in the Middle East without ending Israel's occupation."
Protests were planned near the US Embassy and Consulate in Ankara and Istanbul.
UN Secretary-General Antonio Guterres said the United Nations remains committed to supporting Palestinians and Israelis in resolving their conflict on the basis of UN resolutions, international law and bilateral agreements.
He said the UN is also committed to realizing the vision of two states "living side by side in peace and security within recognized borders, on the basis of the pre-1967 borders, according to his spokesman.
UN spokesman Stephane Dujarric said: "The position of the United Nations on the two-state solution has been defined, throughout the years, by relevant Security Council and General Assembly resolutions by which the Secretariat is bound.'
Germany's foreign minister reacted cautiously to the Middle East peace plan, saying it raises questions that need to be addressed.
Foreign Minister Heiko Maas said in a statement Tuesday that "only a negotiated two-state solution that is acceptable to both parties can lead to lasting peace between Israelis and Palestinians." He added that "on that basis, every impetus laid out in such a way as to set the long-stalled Middle East peace process in motion again is to be welcomed."
Maas said the US proposal "raises questions" that Germany will discuss with its European partners. Those, he said, include the involvement of the two sides in a negotiating process and "its relationship to recognized international parameters and legal positions."
