Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

A police officer has been stabbed and an alleged assailant shot by armed police outside the Houses of Parliament.

Here's what we know so far:

Please allow a moment for the live blog to load

Commons Leader David Lidington has told MPs a "police officer has been stabbed" and the "alleged assailant was shot by armed police" following a "serious" incident within the parliamentary estate.

Minutes later, an emergency services helicopter landed in Parliament Square, as sirens were heard outside.

Iframe:

Air ambulance medics came from the helicopter to assist the casualties.

Two people lay on the ground in the yard. One of them appeared to have had clothes removed as emergency workers attempted to resuscitate the pair.

Parliament Square was closed to traffic.

    I watched the two teams working equally hard to save both the officer and assailant at the same time...an odd feeling

    Lots of people come to Houses of Parliament to do lots of different jobs. One won't go home today. Others will because of him. #Westminster

    London Mayor Sadiq Khan has sent out a video statement. He said: "My heart goes out to those who have lost loved ones and to everyone who has been affected."I want to express my gratitude, on behalf of all Londoners, to the police and emergency services who have shown tremendous bravery in exceptionally difficult circumstances."We stand together in the face of those who seek to harm us and destroy our way of life. Londoners will never be cowed by terrorism."
