An MDA medic who arrived at the scene, described the attack as "a very serious incident."
He said: "The scene was terrible when we arrived. We saw a vehicle near the bus stop that hit pedestrians that were waiting. We saw 6 victims near each other. 2 of them were 6-year-old children who were unconscious with severe multi-trauma injuries.
"A 27-year-old male and 30-year-old male were unconscious, and 2 further victims were conscious with limb injuries. We provided first aid, and performed CPR on the two children.
UK foreign secretary James Cleverly posted a tweet condemning the attack and saying that his thoughts were with the victims' families.
