Moments after people were mowed down on Westminster Bridge, others have been filmed with their phones out in what appears to be an attempt to capture the carnage - and social media is less than impressed.
Video of a woman running up to a motionless victim and steadying herself above him with her phone out has emerged, while others around her can be seen running to seek help, or offering assistance themselves.
Witnesses have described the harrowing scenes as disastrous, and besides the act of terror itself, the use of smartphones has the internet in uproar.
Twitter users have seized on the footage, posing some serious questions and expressing frustration.
"Did that woman just run over there and take out her phone to film?" one asked.
"Only in the UK do people come directly up to a body to take pictures on their phones. That is just sick," another says.

Meanwhile, a selfie-snapping man has also sparked outrage as emergency services were tending to the carnage.
The man, wearing sunglasses, was spotted with his back to a row to capture himself among the action with his phone, on the end of a selfie stick.
"Sir, you with the selfie stick, you need that shoved up your arse," one wrote.
"I've lost even more faith in humanity," another added.
