The ceasefire brokered by U.S. President Donald Trump between Iran and Israel appeared to be holding on Wednesday a day after both countries signalled that their air war had ended, at least for now, Reuters reported.

Each side claimed victory on Tuesday after 12 days of war, which the U.S. joined with airstrikes in support of Israel to take out Iran’s uranium-enrichment facilities.

Trump’s Middle East envoy, Steve Witkoff, said late on Tuesday that talks between the United States and Iran were “promising” and that Washington was hopeful for a long-term peace deal.

“We are already talking to each other, not just directly but also through interlocutors. I think that the conversations are promising. We are hopeful that we can have a long-term peace agreement that resurrects Iran,” Witkoff said in an interview on Fox News’ “The Ingraham Angle” show.

“Now it’s for us to sit down with the Iranians and get to a comprehensive peace agreement, and I am very confident that we are going to achieve that,” he added.

Trump said over the weekend that U.S. stealth bombers had “obliterated” Iran’s programme to develop nuclear weapons. Iran says its enrichment activities are for civilian purposes only.

According to the report, which was produced by the Defense Intelligence Agency, the strikes sealed off the entrances to two of the facilities, but did not collapse underground buildings, said one of the people familiar with its findings.

Some centrifuges remained intact, the Washington Post said, citing an unnamed person familiar with the report.

Trump’s administration told the United Nations Security Council on Tuesday that its weekend strikes had “degraded” Iran’s nuclear programme, short of Trump’s assertion that the facilities had been “obliterated.”

Israeli Prime Minister Benjamin Netanyahu said on Tuesday that the attack had removed the nuclear threat against Israel and he was determined to thwart any attempt by Tehran to revive its weapons program.

“We have removed two immediate existential threats to us: the threat of nuclear annihilation and the threat of annihilation by 20,000 ballistic missiles,” he said.

Iranian President Masoud Pezeshkian said his country had successfully ended the war in what he called a “great victory,” according to Iranian media.

Pezeshkian also told Saudi Crown Prince Mohammed bin Salman that Tehran was ready to resolve differences with the U.S., according to official news agency IRNA.

Israel launched the surprise air war on June 13, attacking Iranian nuclear facilities and killing top military commanders in the worst blow to the Islamic Republic since the 1980s war with Iraq, Reuters reported.

Iran, which denies trying to build nuclear weapons, retaliated with barrages of missiles on Israeli military sites and cities.

Iran has arrested 700 people accused of ties with Israel during the 12-day conflict, the state-affiliated Nournews reported on Wednesday and Iran executed three men on Wednesday, convicted of collaborating with Israel’s Mossad spy agency and smuggling equipment used in an unnamed assassination, the Iranian judiciary’s Mizan news agency reported.

Israel’s military lifted restrictions on activity across the country at 8 p.m. local time (1700 GMT) on Tuesday, and officials said Ben Gurion Airport, the country’s main airport near Tel Aviv, had reopened. Iran’s airspace likewise will be reopened, state-affiliated Nournews reported.

Oil prices edged higher on Wednesday, finding some respite after plummeting in the last two sessions, as investors assessed the stability of the ceasefire and the diminished prospect of an Iranian blockade of the Strait of Hormuz.

The truce appeared fragile: Both Israel and Iran took hours to acknowledge they had accepted the ceasefire and accused each other of violating it.

Trump scolded both sides but aimed especially stinging criticism at Israel, telling the close U.S. ally to “calm down now.” He later said Israel called off further attacks at his command.

Israel’s defence minister, Israel Katz, said he told his U.S. counterpart, Pete Hegseth, that his country would respect the ceasefire unless Iran violated it. Pezeshkian likewise said Iran would honour the ceasefire as long as Israel did, according to Iranian media.

Israeli armed forces chief of staff Eyal Zamir said a “significant chapter” of the conflict had concluded but the campaign against Iran was not over. He said the military would refocus on its war against Iran-backed Hamas militants in Gaza.

Iranian authorities said 610 people were killed in their country by Israeli strikes and 4,746 injured. Iran’s retaliatory bombardment killed 28 people in Israel, the first time its air defences were penetrated by large numbers of Iranian missiles, read the report.
