The US has used up "virtually all" of its stockpile of long-range missiles during the war with Iran, forcing the Pentagon to rely more on "more risky" missions if the conflict continues.

The military's Tactical Missile Systems (Atacms) and Precision Strike Missiles (PrSM) are said to be depleted, prompting concerns amid the current instability in the Middle East.
Two of the sources indicated to Reuters that "virtually all" of these specific weapons have now been utilised after the war started in February.
The missiles are estimated to cost around over $1million each and have also played an important in supplying Ukraine to defend itself against Russia.

The depletion means the Pentagon will have to rely more on piloted bombing missions if Donald Trump keeps up his war on Iran, which is deemed more risky.
The war was only initially believed to last a short while but appears to have no end in sight following repeated failed talks.
Speaking earlier this week, Trump warned Iran it was facing a "last chance" to sign a "good document", as he insisted talks were under way despite Tehran denying negotiations with the US were taking place.
He also claimed the US had been prepared to strike Iran "harder than any attack since World War Two" but instead called off planned attacks.
The White House stated in response that the US had "far more munitions than anyone in the world" and "far more than we need."
Trump said: "Our defence companies are, at this moment, making more munitions than they have ever made before, in addition to expanding their plants and equipment at record levels."
The supply issue has been discussed within the Trump administration, and about how much longer the US can continue striking Iran.
While Reuters has not seen the supply figures, those numbers match internal US data, two of the sources said.
Chief Pentagon spokesman Sean Parnell, said: "America’s military is the most powerful in the world and has everything it needs to execute at the time and place of the president’s choosing.
"We have executed multiple successful operations across combatant commands while ensuring the US military possesses a deep arsenal of capabilities to protect our people and our interests."
