Here are reactions from across the globe:

- 'Critical', 'historic' -

UN Secretary-General Antonio Guterres welcomed the peace deal as a "critical step towards the peaceful settlement of the conflict".

Pakistan Prime Minister Shehbaz Sharif, whose country mediated the talks, told lawmakers: "Today, the world has seen a historic step towards peace. After the darkness of war, the sun of peace has risen."

Turkish President Recep Tayyip Erdogan said he hoped the deal would "fully pave the way toward establishing lasting peace and stability in our region".

Egypt's foreign ministry said in the country "hopes that this agreement will constitute a major turning point toward strengthening mutual trust, laying new foundations for cooperation, creating a supportive environment for peace and advancing diplomatic efforts aimed at addressing remaining regional issues".

- Israel: troops stay -

Israeli Prime Minister Benjamin Netanyahu said the joint US-Israeli military campaign had spared his country from what he called Iran's threat of "nuclear annihilation".

Israel's defence minister said Monday that Israeli forces would remain in Lebanon, Syria and Gaza indefinitely and warned Israel would retaliate with "full force" if Iran attacked it in response to its campaign in Lebanon.

Israel's far-right national security minister Itamar Ben Gvir earlier wrote on X: "(US President Donald) Trump's agreement does not bind us."

- Lebanon: 'diplomatic solutions' -

In a call with Iran's top diplomat, Lebanese President Joseph Aoun said he hoped the agreement would be a "positive step towards reducing tensions and opening the door to diplomatic solutions", the Lebanese presidency said in a statement.

- Saudi: 'non-interference' -

Saudi Arabia's foreign ministry said a lasting deal should be one "that takes into consideration the security interests of regional states, sticking to the principle of non-interference in the interior affairs of other countries".

Qatar's foreign ministry expressed its "full support for all efforts and initiatives aimed at enhancing regional security and stability."

- EU: 'lasting peace' -

European Union chiefs called for a "full restoration" of freedom of navigation in the Strait of Hormuz and said the bloc was ready to contribute to a "lasting peace", and that Lebanon must be included in the final deal.

"There can be no peace in the Middle East while Lebanon is in flames," European Commission President Ursula von der Leyen warned, adding that Hormuz reopening was "essential for regional stability and the global economy" and that a final deal "should end Iran's nuclear and ballistic programmes and its destabilising activities in the region".

Separately, French President Emmanuel Macron said that a UK-French mission was ready to help with Hormuz navigation, while British Prime Minister Keir Starmer said the UK was also ready "to offer support on mine clearance" and that "Iran must never have a nuclear weapon".

- China commends Pakistan -

"China welcomes the agreement reached between the United States and Iran... and expresses appreciation for the mediation efforts made by Pakistan," a foreign ministry spokesperson said.

- Japan: 'Free and safe navigation' -

Prime Minister Sanae Takaichi said she hopes that "free and safe navigation through the Strait of Hormuz will actually be ensured, and that a final agreement on Iran's nuclear issue and other matters will be achieved as soon as possible".

- Spain: End 'senseless' fighting -

"We trust that the peace agreement announced today will help bring an end to this senseless tragedy, that it will be respected by all parties, and that it will mark the beginning of a new chapter in the Middle East," Prime Minister Pedro Sanchez wrote on X.

"Let us celebrate. But let us not forget. And let us learn, once and for all, that war is a failure. Dialogue and diplomacy are the only way forward," he said.
