Thousands of protesters have marched in central London against Israel's military campaign in Gaza.
Activists and supporters of the Palestinian cause gathered outside the Israeli embassy in Kensington, west London, before marching towards Parliament Square.
Israel's latest campaign, dubbed Operation Protective Edge, has claimed hundreds of lives since it began on July 8.
Carrying Palestinian flags and placards with slogans such as Stop the Killing and Free Palestine, the protesters chanted "Israel is a terror state", "Gaza don't you cry, we will never let you die" and "Allahu Akbar" (god is great).
The rally brought central London to a standstill as protesters filed past Hyde Park, down Piccadilly to Trafalgar Square and Whitehall and ending in Parliament Square.
As the march went past Downing Street there were boos and chants of "David Cameron shame on you" and "How many children have to die?"
The statue of South African anti-Apartheid leader Nelson Mandela in Parliament Square was draped with the Palestinian flag as protesters listened to speeches.
Medical student Zahra Legris said she had joined the marching because she was "outraged" at the situation in Gaza.
The 22-year-old Londoner said she had been planning to work in a hospital in the West Bank city of Bethlehem this summer but had been turned away at Ben Gurion airport in Tel Aviv by the Israeli authorities.
She said: "I think it is a shame that has taken so many deaths for people to notice but it's great that there is such an outcry and there are so many people here today. That's really important."
Young protesters chanted against Arab leaders and US president Barack Obama, while others carried a banner which read: "Zionism: Godless & Inhumane".
Aamer Mushtaq, a 28-year-old school IT manager, was selling T-shirts at the protest in support of Palestine.
"We're supporting Palestine because they are being slaughtered, Israel are being unfair the way they are treating the Palestinians," he said.
"We believe the Government should raise their voice and tell Israel to stop killing innocent civilians. This is not a war, this is a slaughter against the Palestinians.
"Everybody can see that this is a human rights issue, it's not a religious issue.
"People have come here from different backgrounds, different cultures, and everybody is united against Israel."
