LONDON - Thousands of people in Britain's capital are taking part in an "emergency demonstration" outside the Prime Minister's home of 10 Downing Street, in order to protest against US President Donald Trump's executive order banning people from seven majority Muslim countries from travelling to the US.

The immigration attracted widespread criticism from world leaders and sparked protests across the US. And now the demonstrations are happening in London's streets.

The protest was organised via a Facebook event page titled "Emergency demo against Trump's #MuslimBan and UK complicity." As of 5:20 p.m. GMT (12:20 ET), 26,000 said they were attending the event while 33,000 said they may be going.

Nearly 20 speakers are attending the event this evening, including human rights campaigner, Baroness Shami Chakrabarti, former Labour leader Ed Miliband, co-leader of the Green Party Caroline Lucas MP, Leader of the Liberal Democrats Tim Farron MP, and singer Lily Allen.

Some of the event information reads:

"Theresa May has decided to ally herself with Donald Trump's bigoted, misogynistic government. She has refused to speak out against Donald Trump's #MuslimBan - even when her own Members of Parliament are targeted. It is not only weak, it is a matter of national shame - disgracing our country across the world.

"There are moments of terrible injustice throughout history where we look back and rightly ask - what did people do? Future generations will look back at the targeting of Muslims - as we look back at the targeting of Jews - with disgust, horror and shame. If we do not speak out, we are complicit.

"Theresa May has betrayed her own people. That doesn't mean we have to. Let's stand in solidarity with those targeted by Donald Trump's hateful government, including the people of this country, outside Downing Street and all over Britain."

Several members of Business Insider attended the event, who, as well as members of the public, sent through photos of what is happening down on the ground:
