The U.S. and Yemen's Iran-aligned Houthis reported separate attacks on shipping on Tuesday as prospects for ending the Iran war appeared to dim, with Tehran saying the Strait of Hormuz would remain closed unless ​Washington accepts its conditions, Reuters reported. 

The attacks, in the Gulf of Oman leading to the strait and at the entrance to the Red Sea — both vital chokepoints for global oil supplies — come as the war shows no signs of ending despite repeated assertions from U.S. President Donald Trump of a deal being imminent.
