Horrifying car crash scene shows victim at Parliament railings

At least two people, including a police officer, are dead after a terror attack in the heart of Westminster.
Paramedics said they treated 10 people who were hit by a 4x4 on Westminster Bridge before it crashed into the gates of Parliament at lunchtime.
An attacker then broke into the grounds of Parliament and stabbed a police officer before he was shot.
Whitehall was put on lock down following the attack and Prime Minister Theresa May is said to have been bundled into a car by a plain-clothes officer and sped to safety.
The Metropolitan Police counter terrorism command is leading the investigation.
Videos, captured by tourists, journalists and workers at the scene, show the chaotic aftermath of the attack.
