Hundreds of people have joined a rally to denounce Britain's air strikes in Syria against Islamic State.
The Stop The War protesters, who gathered at BBC Broadcasting House in London & planned to march to Downing Street, took particular aim at the 66 Labour MPs who crossed the floor to secure the green light for action.
The Socialist Party supplied an open microphone for the event, with over a dozen speakers lining up to voice their anger under the watchful eyes of police.
One speaker, who gave his name as Tony, labelled Prime Minister David Cameron as "insane" & "evil" for pursuing a more aggressive approach.
He said: "You can't bomb your way to peace."
Helen Pattinson, 24, who is part of a group that has been campaigning at schools, questioned the funding for military action.
She said: "How come they can find money to drop bombs on other countries to create refugees… yet they can't find money for health, for education, & for young people to have a decent future?"
Nancy Taaffe, from the Socialist Party, told the crowd: "We've been here before people, haven't we?
"When we're told approximately peace & reconstruction, & then… we see the bodies coming back, we see the bombs in Baghdad market & the sectarian civil war erupted when they kicked the hornets' nest of the Iraq war."
She added: "We say no to the continued violence, we say no to the terror & we say no to the racism that is the fallout of this war."
Ms Taaffe called on Labour politicians to bring a motion back to parliament to cease the air strikes.
She said: "We will back you up with a mass peace movement from outside."
Ursala Khan, 22, of Birmingham, said she was at the rally to show support for innocent Syrians who could be caught up in the strikes.
She said: "If I was in that situation – if I was in Syria – I would hope someone on the other side of the world would stand up for me."
Ms Khan said she does not believe assurances that no civilians will be impacted.
She said: "There is always going to be collateral damage, people will always be killed."
Ms Khan said there are other ways of tackling IS, such as finding out who they sell weapons to & who is buying oil from them.
She said: "I think (David Cameron) probably just wanted an effortless option & probably just wanted to make more money. Typical Cameron."
