Washington, London - The Untied States of America has offered its "full support" to the UK in bringing those behind Wednesday's terror attacks in London to justice. Earlier today, a video showed people have been filmed rushing across the road trying to flee the London terror attack near the UK Parliament as gunshots sounded. White House Press Secretary Sean Spicer made a statement after Donald Trump spoke on the phone to Theresa May following the incident. It comes after a knife man reportedly attempted to storm the Houses of Parliament and members of the public were mowed down on the street outside. Police have since confirmed four people died including a police officer and 20 people were left injured.
