: The United States and Iran reportedly agreed to an "in principle agreement" to extend their two-week ceasefire, which is set to expire on April 22, to provide additional time for diplomacy, AP reported on April 15, citing unnamed regional officials. The United States and Iran could resume peace negotiations in Pakistan later in the week, despite the U.S. blockade of Iranian ports, in effect since April 13, aimed at increasing economic pressure on Iran after the failed April 11 talks.
