A Qatari delegation arrived in Tehran on Sunday, Iranian media and a diplomat said, as part of the mediation process to end the war between Iran and the United States.

Iran's Fars news agency said on Sunday that Tehran has not made a final decision on signing the agreement under discussion with the United States to end the Middle East war.

U.S. President Donald Trump said that a deal with Iran to end the Middle East war could be signed Sunday, and that the strategic Strait of Hormuz would be "open to all" immediately after.

An aid convoy organized by the Vatican envoy to Lebanon that was headed for Christian villages in the country's south was stopped by the Israeli military and forced to change course, a convoy member told AFP.

The United States is "80 to 85 percent" confident of signing a peace deal with Iran in the coming days, a senior official in President Donald Trump's administration said Friday.

Hezbollah said on Friday its fighters had confronted Israeli forces advancing towards a southern Lebanese town, as Israel pressed on with its strikes in Lebanon.

Lebanon reported Israeli strikes on the country's south on Saturday shortly after the Israeli army issued an evacuation warning for 20 locations including the city of Nabatieh ahead of raids there.

Iranian Foreign Minister Abbas Araghchi said that upon finalization, a draft deal with the United States would be signed "remotely", which could happen "in the coming days."

The United States said it downed multiple Iranian drones targeting commercial ships in the Strait of Hormuz early Saturday, hours after both sides said a deal to end the Middle East war was closer than ever.

U.S. President Donald Trump said Friday that Tehran's stated version of a proposed U.S.-Iran deal on stopping the war is not what was agreed to.

Iran's description of the proposed agreement "bears no relation to the truth," Trump said, labeling the Iranians "very dishonorable people to deal with."
