"We'll never allow America and its allies to be threatened with terrorism or nuclear attack," Trump told the crowd, sending a message to the leadership in Tehran.

Nearly 40 military aircraft -- including transport planes like the Hercules C-130 and reconnaissance aircraft -- were parked on the tarmac at the Al Udeid base on June 5, according to images published by Planet Labs PBC and analyzed by AFP.

Indonesian embassies are activating their contingency plan to evacuate Indonesian citizens via land from Iran and Israel, as commercial flights cannot land in both countries.

Trump's move to hit the pause button could open up space for diplomacy, after days of fevered questions about whether or not he would order US military action against Tehran.

A day after stopping short of announcing an evacuation order, the government issued the highest alert level for its citizens in Iran on Thursday, advising them to pack a bag of essential documents and emergency supplies and get in touch via official channels.

Foreigners have rushed to leave both countries after Israel launched an unprecedented bombing campaign last Friday targeting Iran's nuclear and military facilities, sparking retaliation from Tehran.

A week of Israeli air and missile strikes against its major rival has wiped out the top echelon of Iran's military command, damaged its nuclear capabilities and killed hundreds of people, while Iranian retaliatory strikes have killed two dozen civilians in Israel.

Israel, which is not a party to the international Non-Proliferation Treaty, is the only country in the Middle East believed to have nuclear weapons. Israel does not deny or confirm that.

The Foreign Ministry has communicated with Indonesian citizens currently living or staying in Iran and Israel to communicate on contingencies drafted by the government should the situation deteriorate amid escalating conflict between the two countries.

The latest missile barrage came hours after Israel said it had destroyed Iran's internal security headquarters in Tehran, and as it reported a new wave of attacks targeting missile systems and storage sites in the country's west.

"This is the dirty work Israel is doing for all of us," Merz said in an interview with the ZDF broadcaster.

The US president insists Washington has played no part in ally Israel's bombing campaign, but also warned Iran his patience is wearing thin as the conflict enters a sixth day.

The comments fueled questions over whether Washington will join Israel's attacks after insisting it had no hand in the campaign.

Indonesians currently residing in Iran remain on high alert as the Israel-Iran conflict continues with no sign of easing, while officials in the Middle East region have confirmed that no Indonesian nationals have been harmed so far.

Sources told Reuters that Tehran had asked Oman, Qatar and Saudi Arabia to press US President Donald Trump to use his influence on Israeli Prime Minister Benjamin Netanyahu to push for an immediate ceasefire.

After decades of enmity and a prolonged shadow war fought through proxies and covert operations, Israel's surprise assault on Iran last week has touched off the most intense fighting yet and triggered fears of a lengthy conflict that could engulf the Middle East.

Iran's armed forces told residents of Israel to leave the vicinity of "vital areas" for their safety.

The huge wave of Israeli attacks on Iran's military and nuclear facilities on Friday has cast the future of the talks into doubt.

"While we have to postpone this conference for logistical and security reasons, it will take place as soon as possible," Macron said at a press conference.

The above-ground pilot enrichment plant at Natanz has been destroyed, UN nuclear watchdog chief Rafael Grossi told the Security Council on Friday.

The escalating conflict has drawn massive global attention, given the Middle East’s already fragile geopolitical landscape amid the unabating Israeli war and food blockade on Gaza. 

Indonesia has strongly condemned Israel’s recent attack on Iran, describing it as an unlawful act that undermines international law and risks exacerbating existing tensions in the region.

Six Iranian nuclear scientists were killed, Iranian state media reported. Israel said it was working to intercept about 100 drones launched towards Israeli territory in retaliation.

Explosions were heard Friday morning in the Iranian capital, state TV reported, adding that Iran's air defense were at "100 percent operational capacity".

Indonesia has strongly condemned Israel's interception of the Madleen, a British-flagged humanitarian vessel bound for Gaza, calling the action a clear violation of international law and denouncing Israel’s blockade as collective punishment that risks causing mass starvation.

Commission chair Navi Pillay said in a statement accompanying the report: "We are seeing more and more indications that Israel is carrying out a concerted campaign to obliterate Palestinian life in Gaza."

The activist group departed Italy on June 1 aboard the Madleen carrying food and supplies for Gaza, whose entire population the UN has warned is at risk of famine.

Iranian state media reported on Saturday that Iranian intelligence agencies had obtained a large trove of sensitive Israeli documents. Khatib said these were related to Israel's nuclear facilities and its relations with the United States, Europe and other countries, and to its defensive capabilities. 

The British-flagged yacht Madleen, which is operated by the pro-Palestinian Freedom Flotilla Coalition (FFC), was aiming to deliver a symbolic amount of aid to Gaza later on Monday and raise international awareness of the humanitarian crisis there.

Aid distribution in Gaza was halted on Friday after the US and Israeli-backed Gaza Humanitarian Foundation (GHF) said overcrowding had made it unsafe to continue operations, in the latest disruption to its troubled relief effort.
