People 'locked on trains' in Stockholm station after terror attack

At least five people have been killed after terrorists hijacked a truck and rammed shoppers in Stockholm before opening fire on pedestrians today.
The vehicle crashed into a packed shopping centre and burst into flames.
Three men jumped out from the lorry and opened fire before trying to stab pedestrians, witnesses said.
Footage shows two men being tackled to the ground and arrested - but a third suspect is believed to be on the run.
Police have released CCTV of the wanted man wearing a green jacket, white shoes and a grey hoodie and have shut down Stockholm's Central Station and tube network amid fears he is hiding underground.
Officers said the vehicle crashed into a group of people on the street outside a shopping centre in Klarabergsgatan after racing down six streets at about 3pm local time.
Hundreds of shoppers were seen fleeing for their lives after the articulated lorry rammed into the corner of the building.
Horrifying images of the aftermath show blood smeared on the roads and bodies covered by blankets. Dozens more have been injured, some critically.
Footage showed at least two men being detained. Stockholm Police said they are speaking to two people in relation to the attack, but are yet to confirm if they have been arrested.
