While the police say they have not yet identified a motive for Sweden’s worst mass shooting, Reham is alarmed that the man police believe to be the perpetrator attacked a school where Swedish for Immigrants (SFI) courses are taught.

Around 10 people were killed in a school shooting in Örebro. The damage at the crime scene was so extensive that investigators were unable to be more definitive, said Roberto Eid Forest, head of the local police.

The attack on Tuesday - described by Sweden's prime minister as the "worst mass shooting" in the country's history - happened at a school for adults.

Sweden's King Carl XVI Gustaf, Queen Silvia and Swedish Prime Minister Ulf Kristersson visited an education center where at least 10 were killed.
