Most of the protests were centralized in London, England and Madrid, Spain, but other smaller protests took place in various other locations throughout Europe.

The US, UK and other NATO allied countries have been pushing for further intervention in Syria under the pretenses of fighting ISIS. However, western governments have proven that their primary interests in the region involve regime change, and ousting Syrian President Assad from power for their own interests. To make matters worse, the air strikes that have already taken place in the region have threatened the lives of innocent people, killing civilians more often than they kill terrorists.

Stop the War Coalition protest movement said in a statement that, "Prime Minister David Cameron's incoherent proposals for action in Syria will do nothing to weaken ISIL, but will instead inflame the civil war, deepen the misery of the Syrian people, and increase the terrorist risk."
