Video: 'I saw this truck speeding towards us'published at 15:56 British Summer Time 15 July 2016
An eyewitness, who refers to himself as AK, talks to BBC News about what he saw from the scene of the attack.
He says he had to push both himself and his wife on to the pavement, because the truck was less than 10m away.
"There was carnage, absolute carnage. We heard gun shots," he adds.
