Police say arsonists have set four supermarkets on fire in a town south of Stockholm, according to AP. Police spokeswoman Kia Samrell says police have no suspect in the fires in Sodertalje but are investigating whether an anti-American group was responsible. Samrell says two of the stores have been destroyed. The third is seriously ruined but the fourth wasn't damaged. No one was injured in the attacks, which took place early Thursday. The fires were in two different Willys stores, one Ica store and one Tempo store. The supermarkets are Swedish but sell American goods.
