WASHINGTON, Aug ⁠4 (Reuters) – ⁠U.S. President Donald Trump ⁠said there was an “all-day negotiation” on Tuesday with Iran, characterizing ​the talks positively while also threatening to hit Iran “really hard” if a deal ‌with Tehran was not reached.

• “They had an all-day negotiation,” Trump told Fox News’ “@ Night” show.

• “We ⁠are having ⁠very good discussions,” he added.

• Qatar said on Tuesday mediators ​were making progress in efforts to end the Iran war, although Tehran has denied Trump’s assertion that talks were under way.

• The Strait of Hormuz “is going to be ​open very soon,” Trump said, warning that if that did not happen, ⁠Iran ⁠would be hit hard.

• “If ⁠they back ​out again, they are going to get hit really hard,” Trump said.

• Iran ​blocked the Strait of ⁠Hormuz, a main route for energy supplies from the Middle East, after the start of the war.

• The Iran war began on February 28 when the U.S. and Israel attacked Iran and Tehran responded with its own strikes ⁠on Israel and Gulf states that host U.S. bases.

• U.S.-Israeli strikes on ⁠Iran and Israeli attacks on Lebanon have since killed thousands and displaced millions.

• Trump’s rhetoric during the war has been condemned by rights experts when he has threatened to target Iranian civilian infrastructure and when he threatened to destroy their civilization in April.

• Iran has warned that if the U.S. carried out such threats, Iranian forces would target regional energy and economic facilities.

• The 1949 Geneva Conventions ⁠on humanitarian conduct in war prohibit attacks on sites considered essential for civilians.

• Such attacks could amount to war crimes, international law experts in the U.S. said in April, after Trump’s previous threats.
