Iranian and US technical teams working on the implementation of an interim peace deal are ​expected to meet in Doha in the coming days, a source told Reuters on Monday, after tit-for-tat weekend strikes threatened to derail the fragile accord.

Mediators have established ‌communications channels to de-escalate any incidents, and technical talks are set to continue, the source, with knowledge of the discussions, added.

A senior Iranian source said there would be a meeting in Doha on Tuesday, but unlike previous technical talks between Tehran and Washington in Switzerland, the focus would be on managing the Strait of Hormuz and de-escalating tensions.

US President Donald Trump confirmed in a social media post that there would be a meeting in Doha on Tuesday, but gave no details.

The ​US and Iran signed a 14-point memorandum of understanding aimed at ending four months of conflict on June 17, under which both sides agreed to cease hostilities and reopen the strait, through ​which a fifth of the world’s oil and liquefied natural gas typically transits.

Closure of the waterway sent oil prices to above $100 a barrel, pushing up global inflation ⁠and causing a political headache ahead of midterm elections for Trump, who touted falling oil and gas prices in a series of other early morning posts on Monday.

The accord paves the way for 60 days of ​more in-depth talks on thornier issues such as Iran’s nuclear program, although both sides have given conflicting accounts as to what was agreed.

Release of Frozen Iranian Assets

Iranian President Masoud Pezeshkian said on Monday that $6 billion ​out of $12 billion of assets frozen in Qatar would be released following the accord and returned to Iran, Iranian state media reported.

He described the memorandum, which includes waivers for sanctions on Iran’s oil and petrochemical sectors, as “a great victory for the Iranian people.”

The senior Iranian source said Doha and Tehran were in the final stages of agreeing on technicalities for the release of the first $6 billion of frozen assets, which he said would be issued in two tranches.

Oil ​prices rose on Monday with Brent crude futures up almost 1 percent after the weekend tension highlighted the fragility of the US-Iran accord.

White House Press Secretary Karoline Leavitt told Fox News on Monday that US ​envoys Steve Witkoff and Jared Kushner would fly to Doha this week for high-level meetings, which would take place alongside technical talks.

“As far as we’re concerned, we’re holding up our end of the ceasefire. Violence will be ‌met with violence,” ⁠Leavitt added.

But in an indication of the uncertainty around the interim deal, Iran’s Deputy Foreign Minister Kazem Gharibabadi said on Monday, before Trump’s post, that technical working group meetings were not scheduled for this week, according to Iran’s Tasnim news agency.

Consultations with Qatar, including on following up on the implementation of the other side’s commitments, were continuing as usual, he said.

A return to talks would follow several days of strikes and counterstrikes since an Iranian projectile hit a cargo vessel in the Strait of Hormuz on Thursday, with both the US and Iran accusing the other of breaking the interim ceasefire.

Iran, which has sought to exert its ​authority over shipping in the strait, launched missiles and ​drones at US military sites in Kuwait and ⁠Bahrain early on Sunday, shortly after Trump issued his latest threat against Iran.

“There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started,” Trump said on social media.

“If that happens, the Islamic Republic of Iran ​will no longer exist!” he added.

Uncertainty Over Latest Ceasefire Deal in Lebanon

About an hour after Trump’s post, Kuwait’s army said its air defences were ​responding to missile and drone ⁠attacks, while Bahrain said sirens had sounded there.

Iran’s Islamic Revolutionary Guard Corps said US strikes had violated the ceasefire and that American bases in the region would “experience hell in the coming days”.

Meanwhile, Lebanon’s Parliament Speaker Nabih Berri, a key ally of Iran-backed Hezbollah, has cast doubt on a US-brokered agreement between Lebanon and Israel aimed at halting a parallel war there.

Berri warned on Monday that the deal could lead to attempts to divide Lebanese and ⁠said it would ​not be implemented.

The latest round of conflict in Lebanon began after Hezbollah struck Israel early in the war, in what ​it said was support of its backer Iran. Israel’s response has led to mass displacement and more than 4,000 deaths in Lebanon.

Tehran has said ending that conflict and withdrawing Israeli troops from the south of Lebanon are an integral part of any ​deal struck with the US to end the wider war that began with US-Israeli strikes on Iran on February 28.
