(This measure has not been amended since it was introduced. The summary of that version is repeated here.) Expresses the urgent need for a political solution in Yemen consistent with United Nations Security Council Resolution 2216 or as otherwise agreed to by the parties. Denounces the conduct of activities in Yemen and areas affected by the conflict that are inconsistent with the laws of armed conflict, including the deliberate targeting of civilian populations or the use of civilian human shields. Calls on all parties to the conflict to: (1) increase efforts to prevent civilian casualties and increase humanitarian access; and (2) allow for unobstructed access for humanitarian organizations, human rights investigators, medical relief personnel, and journalists. Supports the Saudi-led Arab Coalition's commitments to abide by their no-strike and restricted target list and improve their targeting capabilities. Condemns Iranian activities in Yemen in violation in such resolution and calls on all responsible countries to take necessary measures against Iran, including the interdiction of Iranian weapons to the Houthi rebels and the application of sanctions against Iran. Encourages other governments to join in providing the resources necessary to address the humanitarian crisis.
