17.20 London:The London demo is estimated to be around 15,000 strong. At the rally Kevin Ovenden who was on the Freedom Flotilla, said, 'The question is not if the siege will end, but for how long it will hang on. Israel is attempting to terrorise us, but we will not be deterred.'

At the rally outside the Israeli embassy protesters turned their backs on the embassy before listening to speakers.
Seamas Milne said, 'The governments of Britain, the US and the EU firm up the siege of Gaza. Governments will not change unless we force them. While Iran is threatened with war, Israel is allowed to continue with impunity. This cannot go on, there is no justice while this goes on.'
Sally Hunt, general secretary of the UCU lecturers union said, 'We condemn the attacks. We are shocked and horrified. We send our solidarity to those injured and those on the Rachel Corrie who are being blocked by the Israelis. The blockade stops people seeing their families and denies them their rights. We dont want more words from world leaders – we want action. Free Gaza!'
Jeremy Corbyn MP said, 'I think world opinion has changed and now there is no turning back. Onwards to the freedom of Gaza!'

'The whole Muslim community is treated like terrorists,' she added.

Tony Benn, president of the STWC, called on demonstrators not to lose heart, 'Don't allow cynics to say it's pointless to protest as nothing changes.

'It is shameful that countries like Macedonia and Pakistan managed to get consular representation to flotilla members who were imprisoned but Britain didn't.'
Green MP Caroline Lucas demanded an independent investigation into Israel's piracy. She said, 'The government must suspend the EU Israel association agreement that gives Israel preferential trade while it commits state terrorism. The agreement even has a human rights clause. Enough is enough!'

Eva said, 'We have to resist the demonisation of our Muslim brothers and sisters. We are a movement together.'
Respect councillor Salma Yaqoob said, 'We have to tell the governmentthis is your problem. If the blockade is unjustifiable why aren't British ships breaking it? I promise you I will be on the next flotilla.'

Alison, a GP, says'I want the British government to stop the arms trade with Israel. I want our government to support a boycott of Israel and demand that Israel fully complies with all the UN resolutions passed about the Middle East. I was in the West Bank in November. I saw the apartheid wall and the acres of olive trees chopped down by the Israelis. The repression of the Palestinians must end.'
13.40 Conference against Islamophobia, London: Over 200 people came together in London today for a conference on Islamophobia before joining the march on the Israeli embassy over the attack on the Freedom Flotilla.

Speakers drew the links between goverment policy, media spin and the rise of the racist English Defence League (EDL).
Weyman Bennett, Unite Against Fascism joint secretary, told the conference,'The EDL wants to sow divisions in our towns and cities. But we have to come out and defend the Muslim community and our streets from these racists.'
