The Campaign Against Arms Trade (CAAT) held a vigil outside Downing Street in protest at the United Kingdom’s sale of arms to Saudi Arabia.
The protest marked the seventh anniversary of Saudi Arabia’s involvement in the Yemen conflict.
Speakers at the vigil included author Andrew Feinstein, and a performance from the Raised Voices political choir.
The United Nations has labelled the Yemen conflict as the biggest humanitarian crisis in the world, with 24.1 million people in need of humanitarian aid.
