IRISH Minister for Foreign Affairs Charlie Flanagan has condemned the terrorist attack in London as it is confirmed four people have died and at least 20 are injured.
The Palace of Westminster was evacuated with Parliament on lockdown with MPs in Chambers after a man stormed the palace and stabbed a police officer shortly before 3pm today.
A number of pedestrians were also injured when a vehicle ploughed into the crowd while crossing northbound over Westminster Bridge.
After stabbing a police officer, he was then shot by other police officers.
It’s understood a Northern Irish MP attempted to give first aid to the injured police officer before help arrived.
Sources at the scene told The Irish Post that offices facing the street in Portcullis House had been evacuated.
This evening Ireland's Foreign Affairs Minister Charlie Flanagan said he condemned the attack and announced that as yet, no Irish citizens have been affected.
“I unreservedly condemn the attack outside the Houses of Parliament at Westminster today.
"I deplore the loss of life, and note that the casualties include a police officer killed in the line of duty.
