Khatibzadeh tells Al Jazeera diplomacy is way forward, but US must ensure that Israel stops its attacks on Lebanon.

Iran’s deputy foreign minister says Tehran wants to continue the diplomatic process with Washington, if the United States is serious about respecting their agreement and ensures Israel abides by the terms of the memorandum of understanding (MoU).

“We are ready to move forward step by step, if the other party demonstrates the same seriousness,” Saeed Khatibzadeh told Al Jazeera Arabic in an interview on Friday.

His comments came after talks between the US and Iran that were due in Switzerland on Friday were called off, and US Vice President JD Vance cancelled his planned trip there.

Earlier, officials including mediators Pakistan and Qatar said the two sides would meet in Burgenstock to begin negotiations on a host of issues as outlined in the MoU signed between the US and Iran this week.

Reports said the talks may have been called off after intense fighting between Israel and Hezbollah in southern Lebanon on Friday. Lebanon’s health ministry said Israeli attacks killed at least 47 people since midnight.

Speaking to Al Jazeera, Khatibzadeh denounced the latest Israeli attacks in Lebanon, saying Israel’s “continued war-making” would have “serious and immediate consequences”.

He said Iran was seeking “peace on all fronts, including Gaza”, and explained that Lebanon had been included in the MoU because of its direct connection to the conflict.

Article 1 of the MoU explicitly states that ending the war in Lebanon is an integral part of the broader ceasefire arrangement across all fronts.

“There will be no peace or stability in Lebanon and the region without ending the occupation and Israel’s commitment to international law,” Khatibzadeh added.

On the Strait of Hormuz, he said Iran would continue to provide navigation services in coordination with Oman and in accordance with international law.

He added that Tehran would not impose passage fees during the 60-day period outlined by the agreement, but said a new mechanism for managing the waterway would be introduced afterwards and presented to regional countries.

Khatibzadeh also said that any future agreement must include the release of all frozen Iranian funds.

Esmaeil Baghaei, spokesperson for Iran’s ministry of foreign affairs, said on Friday that the necessary consultations involving the US deal are being carried out through mediators, and that if the conditions for starting negotiations are met an official announcement will be made.

Regarding the Lebanon ceasefire required for talks between the US and Iran to continue, a Hezbollah official told Al Jazeera that the ceasefire would hold if Israel abided by it.

Israel’s ambassador to the US Yechiel Leiter said on X: “Israel remains firmly committed to an immediate ceasefire. If Hezbollah honours the agreement and ceases its hostilities, they will be met with quiet”.
