ANKARA: U.S. ​President Donald Trump warned ​Iran that the United States will likely ​engage in additional strikes on Wednesday night after attacks the previous day."I'll give a little warning: We're going to hit them hard tonight," ‌Trump told ⁠reporters ⁠at the NATO summit in Turkey before his meeting with ​Ukrainian President Volodymyr Zelenskiy.In earlier comments to reporters in Ankara, Trump ​said a memorandum of understanding that served as an initial ceasefire deal between the United States and Iran ​was "over".But he did not explicitly say ⁠Washington would ‌return to full-fledged war and it was ​not ​immediately clear whether the negotiations between the two ⁠sides to turn the ceasefire into a permanent ​deal would still continue or not."I don't ​know if we're going to have a deal. We may just do it without a deal," Trump said before his meeting with Zelenskiy.In a flare-up of hostilities that pushed oil prices up ‌sharply, Iran said it had targeted U.S. military sites in Bahrain and Kuwait after U.S. forces ​struck Iranian ​targets in response ⁠to attacks on tankers in the Strait of Hormuz.The renewed hostilities have also heightened safety and security concerns around the ​Strait of Hormuz, with shipping data showing at least four oil and gas tankers had turned back rather than try to transit the waterway, a vital supply route.
