At least two people are feared dead after a truck drove into a crowd of people in central Stockholm.
Police said a number of people had been hurt in the incident at a department store, which comes after trucks were used in terror attacks in Nice and Berlin last year.
The circumstances surrounding the incident are not yet clear but the Swedish Prime Minister has said that everything indicates it was a ‘terror attack’.
Where is Stockholm?
Stockholm is the capital of Sweden and is located on the southern east coast.
The city is home to around 932,000 people – around 22 per cent of the country’s entire population.
Stockholm is the country’s economic, cultural centre and is also the seat of Swedish government.
The incident occurred in Drottninggatan, a street in a busy shopping district in the centre of the Swedish capital.
Have there been any recent terror attacks in Stockholm?
The crash is close to the scene of a terror attack in 2010 when Taimour Abdulwahab, a Swedish citizen who lived in Luton, blew himself up.
The terrorist, who police concluded acted alone, died on December 11 2010 in the Bryggargatan area. No-one else was killed.
Abdulwahab rigged an Audi car with explosives in the hope that the blast would drive people to Drottninggatan, a busy shopping street, where he was waiting to set off two more devices strapped to his chest and back.
The car bomb never went off and, after setting fire to the Audi, he was unable to detonate the other two explosives as planned.
He made his way down a side street off Drottninggatan and, in an apparent attempt to fix the faulty trigger up his sleeve, set off the bomb on the front of his body, killing only himself.
Where else have vehicles been used in recent attacks?
On 22 March, an attacker drove a car at pedestrians walking over Westminster Bridge, killing five people. Briton Khalid Masood then fatally stabbed unarmed police officer PC Keith Palmer before he was shot dead by an armed police officer.
In December, a truck was driven into a Christmas market in Berlin’s city centre next to the Kaiser Wilhelm Memorial Church, leaving 12 people dead and more than 50 injured. The attacker, Tunisian-born Anis Amri, was killed four days later during a shootout with police in Milan, Italy.
In July 2016, a cargo truck was deliberately driven into crowds celebrating Bastille Day along the seafront in Nice. The attack result in 86 deaths while 434 people were seriously injured. The Tunisian-born attacker was shot dead by French police officers immediately after the attack.
