Trump says US will resume strikes on Iran due to slow progress in talks

US President Donald Trump has said the United States will resume attacks on Iran due to what he described as insufficient progress in negotiations on ending the war.

"We're going to be attacking them, attacking them very hard," Trump said in the Oval Office on 10 June, suggesting that Iran's downing of a US Apache helicopter constitutes grounds for renewed strikes.

"Based on the helicopter, I guess we have the right to do that," he told journalists, as quoted by CNN.

"We hit them hard yesterday. We're going to hit them again hard today, in case you miss it, in case you don't turn on your television set, and we'll see what happens with the deal."

Trump lamented the slow progress of talks with Tehran on a deal to end the war, which he said are still ongoing.

"I've been working with Iran for a number of months. They should sign the deal. It's a good deal," he added.

Later, Trump refused to rule out strikes on civilian infrastructure, including power plants and bridges, expressing frustration that Iran has not yet signed the agreement.

Earlier on 10 June, Trump threatened Iran due to delays in reaching a peace deal with the US.

Trump's remarks came after he said Iran had shot down a US Apache helicopter that was patrolling the Strait of Hormuz overnight, and vowed to respond.
