Iran said Monday it had responded to a new US proposal aimed at ending the war, adding that exchanges were continuing despite Iranian media reports describing Washington's demands as excessive.

"As we announced yesterday, our concerns were conveyed to the American side," foreign ministry spokesman Esmaeil Baqaei said during a press briefing.

The Israeli military began intercepting several boats on Monday morning that are part of a flotilla attempting to break the Gaza blockade.

More than 50 vessels departed from the port in Marmaris last week in what the organizers of the Global Sumud Flotilla described as the final leg of their journey to Gaza's shores.

U.S. President Donald Trump has threatened Iran over its blockade of the Strait of Hormuz, posting an AI-generated picture on his Truth Social platform with Iranian-flagged naval vessels warning, "It Was The Calm Before the Storm."

Trump also warned in comments that Iran should make a deal with the U.S., saying, "if they don't, they're going to have a bad time. A very bad time."

Iranian state television said on Saturday that European countries were in talks with Tehran over transit for ships through the Strait of Hormuz.

Pakistan's interior minister arrived in Tehran on Saturday "to facilitate" the peace talks between Iran and the United States that have stalled despite a fragile ceasefire, Iranian media reported.

Iran's parliament speaker Mohammad Bagher Ghalibaf, who recently emerged as a chief negotiator in talks with the United States, has been appointed to oversee relations with China, Iranian media reported on Sunday.

U.S. authorities on Friday detailed charges against a commander of an Iran-backed Iraqi militia who was allegedly involved in plotting terrorism against Jewish people in Europe, Canada and the United States.

Israel said on Friday that it carried out a strike in Gaza targeting Ezzedine Al-Haddad, who it described as chief of the armed wing of Palestinian movement Hamas.

Since Hamas's October 7, 2023 attack on Israel, the Israeli military and intelligence services have waged an extensive campaign targeting the group's senior political leaders and militant commanders in Gaza and across the region.

Iran 's foreign minister said a lack of trust is the biggest obstacle in negotiations to end the war with the U.S., saying Friday that Tehran would be open to diplomatic help, particularly from China, to help ease tensions.

Iranian Foreign Minister Abbas Araghchi said contradictory messages have "made us reluctant about the real intentions of Americans."

Iran's Foreign Minister Abbas Araghchi said on Friday his government had received messages from the United States indicating that President Donald Trump's administration was open to continuing talks aimed at ending the Middle East war.

"What was said that the United States rejected Iran's proposal or Iran's response to the American proposal was a few days ago, when Mr Trump tweeted and said that it was unacceptable," Araghchi told reporters in the Indian capital.
