Iraqi Prime Minister Ali al-Zaidi called on Monday for an investigation into Saudi Arabia's claim that drones targeting its territory had been launched by pro-Iran groups in Iraq, his spokesman said.

Zaidi directed "the competent security authorities to investigate the statement issued by the ministry of defense of the Kingdom of Saudi Arabia regarding the targeting of the kingdom with drones launched from Iraqi territory", spokesman Sabah al-Numan said in a statement.

Israeli defense minister Israel Katz on Tuesday said that American warplanes used Israeli bases during their attacks on Iran, reiterating that his country was prepared to retaliate if targeted.

Fighting between the U.S. and Iran has been paused since Friday after 13 nights of U.S. strikes on the Islamic republic, after an April ceasefire collapsed.

The Israeli military said on Tuesday it intercepted a drone near the Jordanian border and was looking into its origin.

"A short while ago, the Israeli Air Force intercepted a UAV in the area of the Jordan border," the military said.

Iranian Foreign Minister Abbas Araghchi held separate phone calls on the Strait of Hormuz with his Omani and Saudi counterparts Badr Al-Busaidi and Faisal bin Farhan, state TV said Tuesday.

During the calls, "they stressed the need to strengthen cooperation and advance joint diplomatic efforts to establish stability in the region and eliminate the insecurity imposed on the Strait of Hormuz due to the aggressive actions of the United States," the state broadcaster added.

Palestinian health workers said a woman delivered a stillborn baby in an ambulance after the vehicle was delayed by Israeli soldiers at a checkpoint in the occupied West Bank on Monday.

The Saudi defense ministry said on Monday that its forces had intercepted and destroyed several drones launched from Iraqi territory targeting petroleum facilities.

The ministry went on to say the "terrorist attempts were launched from Iraqi territory and carried out by Iranian-backed terrorist militias", according to an official statement posted on social media.

Mediators have achieved progress in efforts to get the United States and Iran back to negotiations and avert an all-out war in the Middle East, two regional officials said Monday, with a pause in attacks coming after a period of rapidly escalating tensions.

The comments came after neither the U.S. nor Iran reported carrying out any attacks for three straight days — a respite after about two weeks of sustained bombardments that had led to increasing fears of a return to all-out war.

Iran's foreign ministry on Monday said it was not currently involved in negotiations with the United States, despite a halt in recent fighting between the two sides.

"At present, we are not engaged in any negotiations with the United States," said the ministry's spokesman Esmaeil Baqaei at a weekly press briefing, denying reports that Iran had requested talks.

Iran's foreign ministry on Monday said the United States was not involved in recent talks with Oman over the administration of the strategic Strait of Hormuz.

"These talks have no connection with the United States. They are a bilateral matter between Iran and Oman, and they are continuing," said the ministry's spokesman Esmaeil Baqaei in a weekly press briefing, adding that the waterway "remains closed".

Iran's foreign ministry said on Monday it had summoned the French ambassador to Tehran to protest what it described as "interference in Iran's internal affairs" by two diplomats who were briefly detained earlier this month.

"Yesterday, the French ambassador in Tehran was summoned to the Ministry of Foreign Affairs, where it was stressed that the French government must cease such actions and such interference in Iran's internal affairs under misleading labels," said the ministry's spokesman Esmaeil Baqaei in a weekly press briefing, adding that the diplomats had carried out activities "that were in no way justified".
