Doctors and nurses ran from hospital corridors and out to victims today as they responded to the London terror attacks.
Several medics were spotted running through the streets to tend to those caught up in the terrifying attack in Westminster.
The quick response, from medical staff at nearby St Thomas Hospital, was praised by other NHS workers who said they were proud to work for the service.
In one poignant image, a man wearing a stethoscope appears to be deeply affected as he walks through the horrific scene, with his hand in his hair.
In another, women rally together and pile blankets onto a trolley to take down to the victims, as they prepare to admit them into St Thomas Hospital.
Five people have died, including the attacker and one police officer, after the London terror attacks on Wednesday afternoon.
The officer, who was stabbed by the unnamed assailant as he tried to enter Parliament, was named as husband and father PC Keith Palmer.
His colleagues tried in vain to save his life, and were joined by hero MP Tobias Ellwood who attempted to resuscitate the officer, who was stabbed to death.
The attack was launched at about 2.30pm this afternoon, when a driver launched a Hyundai 4×4 into pedestrians on Westminster Bridge, before crashing into the gates of Parliament.
At least 10 people were thought to have been injured initially, but that number has risen.
Parliament was on lockdown for several hours and the Prime Minister was bundled out of the House to be taken to a place of safety.
Patients were taken to St Thomas Hospital, where armed police are now stationed.
Colleagues of the doctors and nurses who rushed to the scene praised their friends on Twitter for their bravery.
Rahee Mapara said she was unbelievably proud to hear of the doctors running from the hospital, while Jess Dingle said she could not praise them enough.
The latest information the hospital shared was via Twitter on Wednesday evening.
The trust posted: ‘Two patients are being treated at St Thomas’ Hospital following today’s security incident in Westminster – one man and one woman.
‘Both patients have been admitted to St Thomas’ and both are in a stable condition. There will be no further statements overnight.’
