The march has drawn criticism from the prime minister and home secretary because it coincides with Armistice Day, when people across the UK remember the moment the guns of the First World War fell silent, Sky News reports.
At noon demonstrators will gather in Hyde Park, around a mile from the Cenotaph, before marching to the US embassy in Vauxhall on the south bank of the Thames, with the demonstration set to end at 4pm.
Organizers have predicted half a million people will gather in the capital in the “biggest demonstration” over the Gaza war, with the police bracing for huge numbers.
The war on Gaza started after the territory’s Resistance movements waged a surprise attack against the occupying entity, dubbed Operation al-Aqsa Storm, in response to its decades-long campaign of bloodletting and devastation against Palestinians.
Over 11,000 Palestinians, mostly women and children, have been killed in Israeli aerial and ground attacks so far.
It has also imposed a complete siege on Gaza, cutting off fuel, electricity, food, and water to more than two million Palestinians living there.
