US, Iran exchange threats as fragile ceasefire set to expire

US and Iran trade threats as tensions escalate before their ceasefire ends. Iran's Parliament Speaker has said the country is prepared to reveal new cards on the battlefield if the ceasefire expires without a deal. The US President has threatened Iran with severe consequences if no agreement is reached. The two countries' peace talks remain in limbo due to the US seizing an Iranian-flagged vessel near the Strait of Hormuz.
