Thousands of people take to the streets of London calling for a permanent ceasefire in Gaza. Protesters heard shouting “from the river to the sea” and some carry placards with the same words displayed. Ahead of the march, police issue leaflets warning people about words or images that could break the law. Report by Blairm.
