London terror attack: Assailant dies from gunshot, more than 40 injured

Two civilians and a police officer were confirmed dead after a vehicle mowed down pedestrians near Britain's Parliament on Wednesday. The attacker also died after authorities brought him down by a gunshot. Experts said that the incident was the latest case of a growing threat of low-tech terrorism.

At least 40 more people were injured after a 4x4 vehicle slammed into pedestrians on the Westminster Bridge before it crashed into a railing near the Parliament. Emergency services were called after the attack.

Based on the latest developments about the incident, the Westminster underground station was shut but it remains open only for interchange. Home Secretary Amber Rudd urged everyone to stay calm and vigilant. Civilians were advised to report to the police if they see anything they are concerned about.

Some of the victims were identified including the 13 students from Edge Hill University in Lancashire. Two of the students who were described as walking wounded were taken to hospital. Two other students had minor injuries.

The Kings College Hospital confirmed that there were eight patients being treated in their facility including six males and two females. Two of the victims were critical while two others were reported stable. According to BBC, St Thomas Hospital admitted two patients who were both stable, while the Royal London Hospital received one patient. A woman that was pulled alive from the River Thames near the bridge was being treated for serious injuries, according to the Port of London Authority.

Acting Deputy Commissioner and head of counter terrorism at the Metropolitan Police Mark Rowley said they assumed that the attacker was inspired by international terrorism. He paid tribute to the police officer named by Scotland Yard as PC Keith Palmer. He said Palmer was someone who left for work at the day of the incident and expected to return home at the end of his shift. Rowley said that Palmer had every right to expect that it would happen. He said that major investigation was under way.

Prime Minister Theresa May described the attack as sick and depraved and that the attack attempted to defeat UK values. She paid tribute to the exceptional men and women of the police force who responded to the attack during her speech on Downing Street. May said that the terrorist chose to strike at the heart of the capital city and the location of the attack was no accident.
