Stockholm

A dozen people were injured in what appeared to be the latest use of a vehicle as a weapon of terror in Europe.

The Swedish Security Service said the attack happened just before 3 p.m. local time. People were seen fleeing the area in panic.

A beer truck was hijacked as it made a delivery nearby, according to the company that owned it. Eyewitnesses reported it being driven at speed along Drottninggatan (Queen Street) before it crashed into the front of a department store.

At least a dozen people were also injured in the incident on Drottninggatan (Queen Street), one of the city's major pedestrian streets, on Friday afternoon.

Swedish Prime Minister Stefan Lofven said it was a terror attack.

One man has been arrested, after police released a CCTV image of a person who may be connected to the case.

In a speech on Friday night, Mr Lofven said Swedish values of democracy and freedom would not be "undermined by hatred".

He also announced the country's border controls had been strengthened.

The girl, from a Hispanic family, was diagnosed in Houston, Texas, by Dr Michael Yafi, a paediatric endocrinologist with the University of Texas. In a written presentation to the European Association for the Study of Diabetes conference in Stockholm, Yafi said she had been brought to his clinic because she was obese.

The girl weighed 35kg (5st 7lbs), putting her in the heaviest 5% of children her age. She was also in the top 5% for height and body mass index (BMI), a measure of obesity.
