Israel's strikes in Lebanon are a "blatant violation of the initial ceasefire agreement," Iranian President Masoud Pezeshkian said in a Thursday post on X/Twitter.
"The repeated aggression by the Zionist entity against Lebanon is a...dangerous sign of deception and lack of commitment to potential future agreements," Pezeshkian added, implying that the peace talks in Islamabad could be negatively impacted by the IDF's actions in Lebanon.
"The continuation of these aggressions will render negotiations meaningless. Our finger remains on the trigger. Iran will never abandon its Lebanese brothers and sisters," the Iranian president wrote.
Meanwhile, Iran's deputy foreign minister Saeed Khatibzadeh told Britain's ITV News on Thursday that, despite reports to the contrary, the Strait of Hormuz is open to all civilian ships who coordinate with Iranian authorities.
Although he did not say so outright, the foreign minister made it clear that this coordination would be necessary for the ships to avoid mines in the strait, which were placed by Iranian forces during the war.
Also on Thursday, Iran's Parliament Speaker Mohammad Bagher Ghalibaf called for a halt to IDF operations in Lebanon in an X post, tying the issue to the upcoming Islamabad talks, saying that "Lebanon and the entire Resistance Axis, as Iran's allies, form an inseparable part of the ceasefire."
"[Pakistani] PM Shehbaz Sharif publicly and clearly stressed the Lebanon issue; there is no room for denial and backtracking," Ghalibaf continued. "Ceasefire violations carry explicit costs and STRONG responses," he wrote. "Extinguish the fire immediately."
Hormuz at near standstill as Iran warns ships to keep to its waters
Iran's Islamic Revolutionary Guard Corps (IRGC) warned ships to keep to a route passing through its territorial waters when crossing the Strait of Hormuz, as traffic on Thursday remained well below 10% of normal volumes.
Mitsui O.S.K. Lines, one of Japan’s big three shipping firms, is among those caught up in the confusion as firms try to work out what impact the US-Iran two-week ceasefire is having.
"It must be confirmed that the safety risks are sufficiently low," President and CEO Jotaro Tamura told Reuters in an interview on Thursday.
The company has recently managed to bring three tankers - one loaded with liquefied natural gas and two with liquefied petroleum gas (LPG) - out of the strait.
Tamura said the company was awaiting guidance from the Japanese government on how to proceed under the two-week ceasefire.
