US forces struck down Iranian drones in a fresh bout of fighting along the Strait of Hormuz, prompting retaliation from Tehran despite a ceasefire agreement remaining in place. US President Donald Trump said earlier that the strait is "going to be open to everybody" and suggested that the military "go back and finish it."
