HOVE MP Peter Kyle has described the dramatic moments following a 'terrorist' attack in Westminster.

At least two people have died after a knifeman brought terror to the heart of Westminster, mowing down pedestrians then stabbing a policeman before he was shot by armed officers.

Eyewitnesses described scenes of terror when gunfire rang out as the attacker approached a second officer within yards of the Houses of Parliament.

Paramedics fought to save his life and that of his victim on the floor of the cobbled courtyard in front of Parliament with Foreign Office minister Tobias Ellwood among those who rushed to help. Two large knives could be seen at the scene.

In a message posted on his Facebook page, the MP wrote: "Thank you to everyone sending me messages at the moment, it's unbelievably kind of you to ask after me.

"I was on my way to vote and passing through Portcullis House when I suddenly heard the noise, shouting, and then security doors open to allow the public to rush in to find safety.

"A group of us came straight back to the office I share with Wes Streeting (MP for Ilford North), and that's where I am now as the building is in lockdown.

"Ever since I became an MP I've always been very aware of the women and men in front of the building I work in, putting themselves in harms way to keep people like me safe. It makes me feel incredibly humble and words cannot describe my gratitude.

"My job right now is to sit quietly in my office and allow these brave officers to do their job. Sitting as I am right now so close to where terror is unfolding, my heart is aching for those outside who are suffering."

Brighton Pavilion MP Caroline Lucas tweeted that she had been locked in the Commons with fellow MPs.
