The United States has imposed new sanctions targeting 14 individuals and companies accused of aiding Iran in acquiring weapons, as Tehran works to rebuild its ballistic missile inventories following U.S.-Israeli attacks. The Treasury Department announced the sanctions on Tuesday.

Meanwhile, President Donald Trump announced on Tuesday that he would extend a ceasefire with Iran, which was set to expire, stating that he would refrain from attacks until discussions with Tehran concluded. Trump also made comments about China potentially providing lethal war supplies to Iran, which would test a U.S. red line.

In other developments, Iran's Foreign Minister Abbas Araqchi stated that the U.S. blockade of Iranian ports was an "act of war" and a violation of the ceasefire. Shipping traffic through the Strait of Hormuz remained largely halted, with only three ships passing in the 24 hours prior.

Iran has reportedly granted its commanders greater autonomy over militias in Iraq, allowing some groups to operate without Tehran's direct approval, a shift attributed to the pressures of the ongoing conflict. The country is also facing significant job losses, with the Deputy Work and Social Security Minister reporting that two million people have lost their jobs due to the war.

In Europe, military planners from over 30 countries are scheduled to hold talks in London to develop plans for reopening the Strait of Hormuz. NATO criticized the nuclear arms policies of Russia and China, urging them to cooperate with the United States for greater stability and transparency.

In the Middle East, Hezbollah claimed to have fired rockets and drones into northern Israel, accusing the Israeli military of violating a ceasefire ahead of U.S.-mediated talks. Israel marked its annual Memorial Day with ceremonies and moments of silence to remember the fallen.
