PANews reported on April 22 that tensions escalated sharply ahead of the expiration of the US-Iran ceasefire agreement, according to CCTV. Iran refused to attend the Islamabad talks scheduled for April 22, accusing the US of obstructing a substantive agreement. US President Trump announced on the same day that he would extend the ceasefire at Pakistan's request, but threatened to continue bombing Iran once the deadline expired, while maintaining the naval blockade and expanding sanctions against Iran. US Vice President Vance canceled his trip to Pakistan. Currently, Iran has blocked the entrance to the Strait of Hormuz and publicly displayed ballistic missiles in Tehran, claiming it is fully prepared for a renewed conflict.
