MP attempts mouth-to-mouth resuscitation of police officer
Conservative MP Tobias Ellwood, a former soldier, is being praised for his attempts to save a police officer who was stabbed in the attack on Westminster on Wednesday (local time).
The Foreign Minister attempted to stem the flow of blood from the officer's wounds and gave him mouth-to-mouth and chest compression.
Images show police, paramedics and the MP working together to deliver CPR to the man. His shirt is completely soaked with blood.
"I tried to stem the flow of blood and give mouth to mouth while waiting for the medics to arrive but I think he had lost too much blood," Mr Ellwood told iTV.
"He had multiple wounds, under the arm and in the back."
Junior doctor Jeeves Wijesuriya
Working alongside the MP was off-duty junior doctor Jeeves Wijesuriya, who was one of the first doctors to arrive at the scene. He believes he treated both a stabbing victim and the attacker.
Dr Wijesuriya was at an interview close-by when he heard screaming, so he ran to help.
He treated two people, saying he was joined by paramedics, police and helicopter emergency services in trying to resuscitate both. One died at the scene, he told Buzzfeed News.
Live news reports captured Dr Wijesuriya as he oversaw the attacker's transfer onto a gurney.
More than seven hours after the attack, Dr Wijesuriya tweeted that he is "Home safe. Humbled by incredible efforts of paramedics, Met police & Hems. Thoughts with those in hospital tonight recieving & giving care."
Hems is an acronym for Helicopter Emergency Medical Service.
Doctors and nurses raced from St Thomas' Hospital to help the injured.
With St Thomas' Hospital located just across the bridge from Parliament, doctors and nurses raced across as soon as they heard of the attack.
Among those who ran across from St Thomas' Hospital to help was junior doctor Colleen Anderson.
She said she was still in shock after treating one fatality and a man with a "massive" head injury, fractures to his legs, a dislocated shoulder and probably internal injuries.
