WASHINGTON — Protests against the ongoing U.S. and Israeli military operations in Iran have grown in cities across the United States and Europe, with demonstrators calling for an end to the conflict that began on Feb. 28.
Thousands of people gathered in major cities including Washington, New York, London and Paris over the weekend, waving placards and chanting slogans such as “No War on Iran” and “Diplomacy Not War.” In the United States, rallies formed part of broader “No Kings” demonstrations that also addressed other policy issues. Organizers reported large turnouts in several locations, while police estimates varied.
Similar demonstrations took place in European capitals. In London, more than 50,000 people marched toward the U.S. Embassy, according to organizers, though official figures were lower. Protesters in Athens marched to the U.S. Embassy, and smaller gatherings occurred in other cities. Demonstrators carried flags and signs opposing the military campaign, with some expressing support for diplomatic solutions.
The protests have occurred as the conflict entered its second month. U.S. and Israeli strikes targeted Iranian military sites, nuclear facilities, leadership and infrastructure, including assets on Kharg Island. Iran responded with missile launches and actions that disrupted shipping in the Strait of Hormuz. The fighting has extended to Israeli ground operations in southern Lebanon against Hezbollah and Houthi missile attacks from Yemen toward Israel.
Hundreds of anti-war demonstrations have been recorded worldwide since late February, according to monitoring groups. In the U.S., rallies took place in cities such as Los Angeles, Chicago and Boston. European protests included events in Germany and other countries. Preliminary reports indicate that demonstrations remained largely peaceful, with no widespread reports of major incidents or arrests in the largest gatherings.
The actions coincide with diplomatic efforts hosted by Pakistan in Islamabad, where officials from regional countries have discussed ceasefire proposals. U.S. forces, including thousands of additional Marines, remain deployed in the Persian Gulf region to support operations and protect shipping lanes. Oil prices have risen sharply amid disruptions, affecting global markets.
As of Monday, protests continued in some cities with smaller follow-up gatherings planned. No unified national or international coordination body has been announced for the demonstrations. U.S. and European authorities have not issued statements on the scale of the weekend events.
