The two-week ceasefire between the US and Iran is due to expire on Wednesday, with uncertainty growing over what comes next.

Iran's parliamentary speaker says Tehran is preparing "new cards on the battlefield" if fighting with the US resumes, signaling a potential escalation as the ceasefire deadline approaches. Meanwhile, US President Donald Trump said on Tuesday that he does not want to extend the ceasefire with Iran. He also accused Iran of violating the truce "numerous times" without providing further details, and said the US will end up with a "great deal" with Iran.

US media report that Vice President JD Vance is set to travel to Pakistan on Tuesday for a possible new round of talks. However, Tehran has not confirmed whether it will send a delegation to Islamabad, casting doubt over whether negotiations will proceed. CGTN brings you the latest.
