Iran is ready to facilitate maritime traffic and ensure shipping security in the Strait of Hormuz, President Masoud Pezeshkian told Japan's Prime Minister Sanae Takaichi in a phone call on Monday, the Islamic Republic News Agency reported.

"Iran is fully prepared to facilitate maritime transit. The main problem stems from the restrictions and obstacles imposed by the United States on Iran's shipping and trade," Pezeshkian said, according to IRNA.

"We will strive to ensure that Japanese vessels can pass without difficulty and with greater ease," he added.

Pezeshkian said Iran had always viewed diplomacy as the most effective way to resolve existing issues, but that the United States' failure to honor its commitments and Israel through its "destabilizing actions," had challenged diplomatic efforts.

Iran's negotiating team is stopping message exchanges with the United States through mediators over Israel's attacks on Hezbollah in Lebanon, IRGC-affiliated Tasnim News Agency reported on Monday.

There will be no talks until Iran's demands on the cessation of Israeli operations in Lebanon and Gaza are met, the report said, adding that Tehran considers the attacks on the Lebanese group a violation of the April 8 ceasefire with the US.

Iran and its regional allied groups "have placed on their agenda the complete closure of the Strait of Hormuz and the activation of other fronts, including the Bab al-Mandab Strait," to punish Israel and its supporters, Tasnim's report added.

Japan's Prime Minister Sanae Takaichi said on Monday that she urged President Masoud Pezeshkian during a telephone call to ensure that all ships, including those from Japan and other Asian countries, can pass through the Strait of Hormuz freely and safely as soon as possible.

"I strongly hope Iran will seize this opportunity firmly and continue to demonstrate the utmost flexibility so that an agreement can be reached as soon as possible," Takaichi said on X.

"President Pezeshkian explained Iran's views, including prospects for the future. On that basis, we agreed to continue close communication going forward," she added.

US forces intercepted two Iranian ballistic missiles targeting American forces based in Kuwait late on Sunday, US Central Command (CENTCOM) said on Monday.

"These missiles were immediately defeated and no American personnel were harmed," CENTCOM said in a statement.

"U.S. Central Command remains vigilant and will continue to protect our forces from Iranian aggression while supporting the ongoing ceasefire," it added.

Iranian Foreign Minister Abbas Araghchi said on Monday that the ceasefire between Iran and the United States covered “all fronts,” including Lebanon.

“The ceasefire between Iran and the US is unequivocally a ceasefire on all fronts, including in Lebanon,” he said.

The foreign minister said a violation on one front would amount to a violation of the ceasefire on all fronts.

“The US and Israel are responsible for the consequences of any violation,” Araghchi warned in a post on X.

Israeli Prime Minister Benjamin Netanyahu said in a statement earlier in the day that he had ordered the military to strike targets belonging to Iran-backed Hezbollah in Beirut’s southern suburb of Dahiyeh.
