Iran’s main news agency IRNA reports that the country’s top diplomat, Foreign Minister Abbas Araghchi, departed Islamabad, Pakistan, late Sunday for Moscow, where he’ll discuss regional developments and bilateral Iran-Russia relations with senior Russian officials.

Iran’s Ambassador to Moscow Kazem Jalali also posted on Telegram that Araghchi hopes to meet with Russian President Vladimir Putin during his visit Monday.

Iranian media reports that Foreign Minister Abbas Araghchi has conveyed written messages to the United States via Pakistan during his recent regional tour.

According to Iran's semi-official Fars News Agency, the messages outline Tehran’s “red lines” in peace negotiations, including issues related to its nuclear program and the Strait of Hormuz.

Fars added that the exchange of messages does not constitute negotiations but is an “initiative” by Iran to clarify the situation in the region and the country’s red lines.

Meanwhile, the semi-official Tasnim News Agency reported that Araghchi has returned to Islamabad to continue consultations with Pakistani officials, and that the visit is not related to nuclear talks.

Tasnim said conveying Iran’s conditions for ending the war to Pakistan, the government of which is acting as a mediator, is one of the “key objectives” of the trip.

Araghchi would discuss the legal status of the Strait of Hormuz, compensation, guarantees against further military action, and the lifting of the naval blockade of the Strait of Hormuz, according to Tasnim.

Iran’s foreign minister, Abbas Araghchi, arrived in Islamabad Sunday following talks with Oman’s sultan in Muscat as regional diplomatic efforts to end the war continue, according to Iran's semi-official Tasnim News Agency.

Araghchi first arrived in Islamabad on Friday evening and met with Pakistan’s prime minister, foreign minister and army chief, in what Iranian media described as an effort to convey Tehran’s position on the conflict.

Tasnim also reported that Araghchi held phone calls with his Qatari and Saudi counterparts to discuss developments surrounding the ceasefire and ongoing diplomatic efforts related to the conflict between Iran and the U.S.

Oman has for years acted as a back channel for different negotiations between Tehran and Washington.

Since the U.S.-Israeli attacks on Iran began on February 28, Iran has launched strikes against several countries in the region, including Qatar and Saudi Arabia. Both countries are influential Arab states with close ties to the U.S., despite not being direct parties to the conflict.

Israel Defense Forces spokesperson Avichay Adraee on Sunday ordered the residents of seven Lebanese villages to the north of the Litani River to evacuate, saying the IDF was planning to "act forcefully" against alleged Hezbollah targets in the area.

"Anyone present near Hezbollah elements, their facilities, or their combat means is endangering their life," Adraee wrote.

President Donald Trump said in a Thursday social media post that he ordered the Navy to "shoot and kill" any boats putting mines in the waters of the Strait of Hormuz.

"I have ordered the United States Navy to shoot and kill any boat, small boats though they may be (Their naval ships are ALL, 159 of them, at the bottom of the sea!), that is putting mines in the waters of the Strait of Hormuz," Trump wrote.

"There is to be no hesitation. Additionally, our mine 'sweepers' are clearing the Strait right now. I am hereby ordering that activity to continue, but at a tripled up level!" Trump added.

There are currently no U.S. Navy ships in the Strait of Hormuz , but there are 17 U.S. Navy ships east of the strait in the Gulf of Oman and the Arabian Sea. So far, all of the previous attacks on Iranian mine-laying ships have been from the air.

The president’s post comes a day after the Washington Post reported that a Pentagon assessment found that clearing Iranian mines from the Strait of Hormuz could take as long as six months. 

It is currently unclear if Iranian mine-laying operations remain underway in the Strait amid the ceasefire. The regime previously declared that it had mined a wide swath of the strait off of the coast of Oman.
