U.S. and Iran Presidents Sign Ceasefire Agreement as Trump Warns Attacks Could Resume

The U.S. and Iran have signed an interim ceasefire agreement their officials say is now in effect, according to Reuters-syndicated reporting and CBS News.

The agreement is the strongest public confirmation yet that the earlier reported U.S.-Iran memorandum has moved from draft and scheduling dispute into implementation. But it is still an interim MOU, not a final settlement.

What happened

Reuters reported that the U.S. and Iran released the text of a signed interim agreement on Wednesday, June 17. The Business Standard carried the Reuters report, saying both President Donald Trump and Iranian President Masoud Pezeshkian digitally signed the memorandum in English and Farsi.

CBS News separately reported that a White House official said the U.S. and Iran remotely signed the memorandum and that it is now in effect. Iran's foreign ministry spokesperson Esmaeil Baghaei also confirmed the signing through Iranian state media, according to CBS.

What is in the agreement

The 14-point memorandum extends the ceasefire for 60 days while the two sides try to negotiate a final truce. Reported provisions include an immediate halt to military operations on all fronts, including Lebanon, reopening maritime traffic through the Strait of Hormuz, lifting the U.S. naval blockade of Iranian ports, sanctions waivers and talks over Iran's nuclear program.

Iran also undertakes not to build nuclear weapons and agrees to down-blending enriched uranium under IAEA oversight, according to the Reuters account. Those are implementation claims that will still need monitoring and verification.

What Trump said

Trump framed the MOU as conditional. Reuters reported he threatened to resume attacks if Iran failed to honor the agreement. CBS also reported that Trump said the U.S. could go back to bombing if the wider 60-day talks fail.

Radio Free Europe/Radio Liberty reported a similar line from the G7 summit: Trump said the memorandum was not final and that Washington could return to military action if he was dissatisfied with Iran's implementation.

What is confirmed

Confirmed: U.S. and Iranian officials say the presidents signed the memorandum. Confirmed: the MOU is described by U.S. officials as in effect. Confirmed: Trump has publicly warned that attacks could resume if Iran violates the terms.

Also confirmed: the agreement is interim. It creates a 60-day window for a broader truce and nuclear negotiations; it does not settle every military, nuclear, sanctions or Lebanon question by itself.

What is not confirmed

Not confirmed: that the full agreement will hold through the 60-day period. Not confirmed: that Israel, Hezbollah and every aligned force will treat the Lebanon language the same way. Not confirmed: that sanctions relief, asset releases and Hormuz shipping rules will be implemented without disputes.

That is the key distinction for the headline: the ceasefire agreement is signed, but the war-risk has not disappeared.

What to watch next

Watch for the full text, official implementation steps around Hormuz, IAEA verification language, the status of the planned Switzerland ceremony, and whether Israel and Hezbollah stop or continue operations in Lebanon.

NoDechev rating: signed interim agreement, not final peace. The signing is confirmed by U.S. and Iranian officials; compliance and the 60-day follow-on deal remain the real test.
