Up to 15,000 people will march to Kensington's Israeli Embassy tomorrow in protest at the 'ongoing occupation and siege of Gaza'.
Around 1,000 police officers will be policing the event from Whitehall to Kensington High Street which will be closed from noon until 6.30pm, July 19.
The march, which is expected to attract between 10,000 and 15,000 people, begins in Whitehall and will finish at Kensington High Street by the junction with Kensington Palace Gardens where there will be a rally and speeches.
A Kensington and Chelsea Council spokeswoman said: "The event means the police have decided to close Kensington High Street from about noon, but, in light of representations from the community, the south pavement will be protected by barriers to allow the community and businesses to carry on as normal."
More than 10,000 people demonstrated outside the Israeli embassy, on July 11, as Israeli assaults on Gaza continued and the Palestinian death toll mounted.
Sarah Colborne, Director of Palestine Solidarity Campaign, said: "London has already shown its outrage at Israel’s attacks on the mostly refugee population of Gaza, with people turning out in their thousands last week.
"Saturday’s national demonstration will give people from across the country the chance to say enough is enough, Israel’s siege of Gaza and its occupation of Palestinian land has to end now. People want justice and freedom for the Palestinians, and they will be voicing this in their thousands on Saturday.”
The National Demonstration for Gaza has been called by the following organisations:
Palestine Solidarity Campaign, Friends of Al-Aqsa, Stop the War Coalition, British Muslim Initiative, Palestinian Forum in Britain, Muslim Association of Britain, Islamic Forum in Europe, Israeli Coalition against House Demolitions (UK).
