LONDON, June 15 (Reuters) - Ensuring the Strait of Hormuz is safe from mines could delay a return to normal shipping traffic by weeks following a deal to reopen the waterway, shipping and maritime security sources say.

The operation by conventional minesweepers and state-of-the-art underwater drones could continue for 40 to 50 days before many insurance, shipping or oil companies are confident enough to sail through, according to assessments from five Western maritime security sources.

ANKARA, June 15 (Reuters) - Foreign Minister Hakan Fidan told Iranian counterpart Abbas Araqchi in a call on Monday that Turkey hoped further talks with the U.S. would yield positive outcomes after an Iran-U.S. deal to halt the war, a Turkish diplomatic source said.

Fidan also warned against "provocations" that could derail the agreement and vowed that Turkey would continue supporting efforts for regional peace, the source said. Araqchi thanked Turkey for its efforts in the negotiation process, the source added.

ANKARA, June 15 (Reuters) - Foreign Minister Hakan Fidan will repeat Turkey's offer to host talks between Russia and Ukraine on a visit to Moscow this week at which he will also discuss Black Sea shipping safety and the South Caucasus, a diplomatic source said on Monday.

The visit on Tuesday and Wednesday comes ahead of Turkey hosting a NATO summit on July 7-8, and after Kyiv asked Ankara in April to mediate by hosting a leaders' level meeting. Turkey has maintained cordial ties with Moscow and Kyiv since Russia's invasion in 2022.

LONDON, June 15 - This is what the U.S. and Iran, along with mediator Pakistan, have said about what is in the preliminary deal they have announced to end the war.

HOW THE DEAL WILL BE PHASED AND WHAT HAPPENS WHEN:

• Pakistan's Prime Minister Shehbaz Sharif said both sides had declared an immediate and permanent end of all military operations.

• All sides have said the memorandum of understanding on an end to the war will be signed in Switzerland on Friday. Iran's Deputy Foreign Minister Kazem Gharibabdi said the memorandum would then be published.

BERLIN, June 15 (Reuters) - Israel expects more orders for air and missile defence systems from European countries soon, with at least one contract expected within weeks, a senior official at Israel's defence ministry said.

Demand continues to soar as European nations perceive a greater threat from Russia and seek to bolster their air defences, the official said, driving interest in systems designed to counter intermediate-range ballistic missiles and short-range rockets.

Iran and the United States said ships had again started moving through the Strait of Hormuz -- with President Donald Trump saying the vital oil route would be "completely open" by Friday -- after Washington and Tehran announced a deal to end the Middle East war.

The reopening of one of the world's most important energy chokepoints would mark a major step toward ending months of deadly conflict and economic turmoil triggered by US-Israeli strikes on Iran in late February.

DUBAI, June 15 (Reuters) - The United Arab Emirates called for full implementation of the U.S.-Iran preliminary deal to end their war, including an immediate halt to hostilities and ensuring freedom of navigation through the Strait of Hormuz, the foreign ministry said on Monday.

The ministry statement stressed the importance of dialogue, diplomacy and adherence to international law following the U.S.-Iran memorandum of understanding.

The UAE was affected by the conflict, with Iranian strikes hitting shipping and energy infrastructure linked to the country during the war.

The United States and Iran have agreed to a preliminary peace deal and an end to military operations on all fronts, signalling the apparent end to more than three months of war in the Middle East.

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".

GENEVA, June 15 (Reuters) - The United Nations' human rights chief on Monday welcomed the announcement of a peace deal between the United States and Iran, and urged for maximum restraint by all sides in the region.

"I welcome the announcement that the United States and Iran have agreed on a peace deal that provides for an immediate and permanent ceasefire, the reopening of the Strait of Hormuz, and a framework for further negotiations," said human rights chief Volker Turk.

PARIS/FRANKFURT, June 15 (Reuters) - ECB President Christine Lagarde on Monday welcomed news of a U.S.-Iran ceasefire, saying it could help reopen the Strait of Hormuz, although fellow policymaker Joachim Nagel cautioned it would bring no immediate relief to high euro zone inflation.

U.S. and Iranian officials said overnight they had reached an agreement to end their war and reopen the Strait, a gateway for energy shipment, in a preliminary pact that sent oil prices falling and curbed bets on ECB rate hikes.
