Iran’s top security body has warned of a predetermined countermeasure in the event of a US violation of the newly signed memorandum of understanding between the two countries.

Iranian President Masoud Pezeshkian has warmly welcomed the recent message of the Leader of the Islamic Revolution Ayatollah Seyyed Mojtaba Khamenei, regarding the negotiation process and the agreement to end the war.

Hamas spokesperson Hazem Qassem on Thursday called on US President Donald Trump to pressure the Zionist regime’s government to stop its ongoing violations of the Gaza ceasefire agreement to allow the implementation of the remaining components of the plan to end the war.

A series of intense Zionist regime’s airstrikes targeting multiple towns across southern Lebanon from midnight through the early morning hours left 18 people martyred and 33 others wounded, according to a preliminary toll released by the Lebanese Ministry of Public Health’s Emergency Operations Center. The attacks mark another escalation despite the existing ceasefire agreement.

Leader of the Islamic Revolution Ayatollah Seyyed Mojtaba Khamenei says Iranian officials have made extensive efforts out of compassion and goodwill to reach a memorandum of understanding with the US, while the American president has used various leverage points out of desperation.

Iranian President Masoud Pezeshkian has hailed the Islamabad Memorandum of Understanding signed with the United States as a “historic document” and a demonstration of Iran’s strength on the world stage.

The speaker of Iran’s Parliament and head of the Islamic Republic’s negotiating team says the country is pursuing a "diplomacy of strength" backed by its battlefield victory over the United States and the Israeli regime, stressing that negotiations have served as a method of struggle rather than a sign of retreat.

The Palestinian Islamic Jihad resistance movement says the US President Donald Trump's administration must be held accountable for the atrocities and acts of aggression being perpetrated by Zionist regime’s occupation forces against ordinary Palestinians in the war-ravaged Gaza Strip.

The memorandum of understanding between Iran and the United States has now been formally signed by the presidents of both countries, with the text finalized and the agreement officially in effect, Iran's Foreign Ministry spokesman announced on Wednesday.

The Zionist regime’s forces carried out a series of coordinated raids across multiple cities, towns, and refugee camps in the occupied West Bank and Al-Quds early Thursday, conducting home searches, vehicle inspections, arrests, and firing tear gas, stun grenades, and live ammunition.
