The United States launched fresh attacks against Iran on Thursday, prompting Tehran to retaliate, as US leaders accused their counterparts of dragging out negotiations for a deal to end the three-month war. The second straight day of tit-for-tat strikes, with Iran targeting US bases across the Gulf, sent oil prices rising again. US President Donald Trump, who had repeatedly said negotiations with Tehran were close to an end, said on Wednesday that Iran keeps “playing us for suckers” and will now “have to pay the price”.
