If the US decides to support Israel more directly in its attack on Iran, one option for Washington would be to provide the "bunker-buster" bombs believed necessary to significantly damage the Fordo nuclear fuel enrichment plant, built deeply into a mountain.

Such a bomb would have to be dropped from an American aircraft, which could have wide-ranging ramifications, including jeopardizing any chance of Iran engaging in Trump's desired talks on its nuclear program. Israeli officials have also suggested that there are other options for it to attack Fordo as it seeks to destroy Iran's nuclear capabilities.

But aside from a commando attack on the ground or a nuclear strike, the bunker buster bomb seems the most likely option.

What is the bunker-buster bomb? "Bunker buster" is a broad term used to describe bombs that are designed to penetrate deep below the surface before exploding. In this case, it refers to the latest GBU-57 A/B Massive Ordnance Penetrator bomb in the American arsenal. The roughly 30,000 pound (13,600 kilogram) precision-guided bomb is designed to attack deeply buried and hardened bunkers and tunnels, according to the US Air Force.

It's believed to be able to penetrate about 200 feet (61 meters) below the surface before exploding, and the bombs can be dropped one after another, effectively drilling deeper and deeper with each successive blast.

The bomb carries a conventional warhead, but the International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility.

However, Israeli strikes at another Iranian nuclear site, Natanz, on a centrifuge site have caused contamination only at the site itself, not the surrounding area, the IAEA has said.

How tough a target is Fordo? Fordo is Iran's second nuclear enrichment facility after Natanz, its main facility. So far, Israeli strikes aren’t known to have damaged Natanz’s underground enrichment hall, nor have the Israelis targeted tunnels the Iranians are digging nearby.

Fordo is smaller than Natanz, and is built into the side of a mountain near the city of Qom, about 60 miles (95 kilometers) southwest of Tehran. Construction is believed to have started around 2006 and it became first operational in 2009 — the same year Tehran publicly acknowledged its existence.

In addition to being an estimated 80 meters (260 feet) under rock and soil, the site is reportedly protected by Iranian and Russian surface-to-air missile systems. Those air defenses, however, likely have already been struck in the Israeli campaign.

Still, Israeli Prime Minister Benjamin Netanyahu has said the goal of attacking Iran was to eliminate its missile and nuclear program, which he described as an existential threat to Israel, and officials have said Fordo was part of that plan.

"This entire operation ... really has to be completed with the elimination of Fordo," Yechiel Leiter, Israel's ambassador to the US, told Fox News on Friday.

Why does the US need to be involved? In theory, the GBU-57 A/B could be dropped by any bomber capable of carrying the weight, but at the moment the US has only configured and programed its B-2 Spirit stealth bomber to deliver the bomb, according to the Air Force.

The B-2 is only flown by the Air Force, and is produced by Northrop Grumman.

According to the manufacturer, the B-2 can carry a payload of 40,000 pounds (18,000 kilograms) but the US Air Force has said it has successfully tested the B-2 loaded with two GBU-57 A/B bunker busters — a total weight of some 60,000 pounds (27,200 kilograms).

The strategic long-range heavy bomber has a range of about 7,000 miles (11,000 kilometers) without refueling and 11,500 miles (18,500 kilometers) with one refueling, and can reach any point in the world within hours, according to Northrop Grumman.

Whether the US would get involved is another matter.

At the G7 meeting in Canada, Trump was asked what it would take for Washington to become involved militarily and he said: "I don't want to talk about that."

In a weekend interview with ABC News, Israeli Ambassador Leiter was asked about the possibility of the US helping attack Fordo and he emphasized Israel has only asked the US for defensive help.

"We have a number of contingencies ... which will enable us to deal with Fordo," he said.

"Not everything is a matter of, you know, taking to the skies and bombing from afar."



Gazans’ Daily Struggle for Water After Deadly Israeli Strike

Gazans’ Daily Struggle for Water After Deadly Israeli Strike

The al-Manasra family rarely get enough water for both drinking and washing after their daily trudge to a Gaza distribution point like the one where eight people were killed on Sunday in a strike that Israel's military said had missed its target.

Living in a tent camp by the ruins of a smashed concrete building in Gaza City, the family say their children are already suffering from diarrhea and skin maladies and from the lack of clean water, and they fear worse to come.

"There's no water, our children have been infected with scabies, there are no hospitals to go to and no medications," said Akram Manasra, 51.

He had set off on Monday for a local water tap with three of his daughters, each of them carrying two heavy plastic containers in Gaza's blazing summer heat, but they only managed to fill two - barely enough for the family of 10.

Gaza's lack of clean water after 21 months of war and four months of Israeli blockade is already having "devastating impacts on public health" the United Nations humanitarian agency OCHA said in a report this month.

For people queuing at a water distribution point on Sunday it was fatal. A missile that Israel said had targeted fighters but malfunctioned hit a queue of people waiting to collect water at the Nuseirat refugee camp.

Israel's blockade of fuel along with the difficulty in accessing wells and desalination plants in zones controlled by the Israeli military is severely constraining water, sanitation and hygiene services according to OCHA.

Fuel shortages have also hit waste and sewage services, risking more contamination of the tiny, crowded territory's dwindling water supply, and diseases causing diarrhea and jaundice are spreading among people crammed into shelters and weakened by hunger.

"If electricity was allowed to desalination plants the problem of a lethal lack of water, which is what's becoming the situation now in Gaza, would be changed within 24 hours," said James Elder, the spokesperson for the UN's children's agency UNICEF.

"What possible reason can there be for denying of a legitimate amount of water that a family needs?" he added.

COGAT, the Israeli military aid coordination agency, did not immediately respond to a request for comment.

Last week, an Israeli military official said that Israel was allowing sufficient fuel into Gaza but that its distribution around the enclave was not under Israel's purview.

THIRSTY AND DIRTY

For the Manasra family, like others in Gaza, the daily toil of finding water is exhausting and often fruitless.

Inside their tent the family tries to maintain hygiene by sweeping. But there is no water for proper cleaning and sometimes they are unable to wash dishes from their meager meals for several days at a time.

Manasra sat in the tent and showed how one of his young daughters had angry red marks across her back from what he said a doctor had told them was a skin infection caused by the lack of clean water.

They maintain a strict regimen of water use by priority.

After pouring their two containers of water from the distribution point into a broken plastic water butt by their tent, they use it to clean themselves from the tap, using their hands to spoon it over their heads and bodies.

Water that runs off into the basin underneath is then used for dishes and after that - now grey and dirty - for clothes.

"How is this going to be enough for 10 people? For the showering, washing, dish washing, and the washing of the covers. It's been three months; we haven't washed the covers, and the weather is hot," Manasra said.

His wife, Umm Khaled, sat washing clothes in a tiny puddle of water at the bottom of a bucket - all that was left after the more urgent requirements of drinking and cooking.

"My daughter was very sick from the heat rash and the scabies. I went to several doctors for her and they prescribed many medications. Two of my children yesterday, one had diarrhea and vomiting and the other had fever and infections from the dirty water," she said.
