U.S. President Donald Trump has declared that the ceasefire with Iran is over, saying he has no interest in negotiating another agreement with Tehran.

Trump's remarks came after reports of overnight U.S. military strikes on Iran and Iran's claims that it had retaliated by targeting American military bases in the Gulf region, escalating tensions in the Middle East.

Speaking to reporters during the NATO Summit in Ankara, Türkiye, Trump said that, in his view, the ceasefire had effectively ended. He criticized Iran's leadership and argued that there was no longer any purpose in continuing negotiations with Tehran.

Trump further accused Iran of intending to use nuclear weapons if it were ever to acquire them, describing the Iranian leadership as unreliable and aggressive. He stated that further negotiations would be a waste of time.

He added that his special envoy Steve Witkoff and his son-in-law Jared Kushner remain in contact with Iranian officials, but said the decision on whether talks resume now rests with Tehran.

Trump also alleged that Iran had repeatedly misrepresented the June 17 ceasefire agreement, claiming that while both sides had agreed Iran would not pursue nuclear weapons, Tehran had publicly denied such an understanding.

Following Trump's announcement, global crude oil prices rose by around 5%, reflecting growing concerns that renewed tensions in the Middle East could disrupt global energy markets.
