Tens of thousands of anti-war demonstrators have protested all over the world to mark the fourth anniversary of the start of the second Iraq war.
A rally in Washington was just one of many planned over several days. The anniversary itself is on Tuesday.
It echoed a similar protest 40 years ago, when anti-war activists marched on the Pentagon, campaigning for the US to get out of Vietnam.
They also marched in Copenhagen, Prague and cities all over Spain, including in the capital Madrid.
Among the anti-war messages were calls for nuclear disarmament and the closure of the US detention centre in Guantanamo Bay. The conservative government of Spain at the time was a staunch supporter of George W. Bush, despite widespread disquiet among the Spanish people.
In Budapest, thousands of people held a torchlit vigil. It began in the Hungarian capital exactly four years ago, when anti-war campaigners stood together in the shape of the international symbol for peace, just days before troops moved into Iraq.
Their actions then inspired thousands of other demonstrators in cities around the world.
