LONDON, ENGLAND — Four people, including a London police officer, are confirmed dead after a knife wielding suspect launched an attack outside the U.K.’s parliament on Wednesday. In addition to those killed, at least twenty others are confirmed injured, three of which are police officers.
London police were called to the Parliament building at around 2:40 p.m. local time (10:40 a.m. EST) in response to reports of a vehicle crashing into a crowd at Westminster Bridge.
Police say the driver of the vehicle mowed down pedestrians on London’s Westminster Bridge, leapt from the car and began hacking passersby with a knife.
The attacker was shot by police and later confirmed dead.
Deputy Commisssioner and Head of Counter Terrorism Mark Rowley told reporters that all the information they’ve received leads them to believe that only one attacker was involved.
“Sadly, I can confirm that now four people have died. That includes the police officer who was protecting Parliament, and one man that we believe to be the attacker who was shot by police fire at the scene,” said Rowley. “We are satisfied at this stage that it looks like there was only one attacker. But it would be foolish to be overconfident early on.”
“This is the day we have planned for but we hoped would never happen,” Rowley continued. “Sadly, it’s now a reality.”
According to a spokesperson for the National Security Council, president Trump was briefed on the attack shortly after it occurred and immediately called British Prime Minister Theresa May where he offered his condolences.
In addition to offering his condolences, Trump promised May the full cooperation and support of the US government in “responding to the attack and bringing those responsible to justice.”
The US State Department echoed Trump’s support for the U.K. in a statement issued shortly after the attack.
“We condemn these horrific acts of violence, and whether they were carried out by troubled individuals or by terrorists, the victims know no difference,” US Secretary of State Rex Tillerson said in the statement.
White House press secretary Sean Spicer also condemned the attack during his daily press briefing on Wednesday, and praised the quick response by police officials and first responders on the scene.
