A group which it said was close to Al-Qaida has claimed the petrol bomb attack on an Iraqi polling station in Stockholm, a leading Swedish newspaper reported Friday.
"A Swedish group claiming to be a branch of the terror network Al-Qaida has claimed the attack on an Iraqi election office in Kista," the Dagens Nyheter daily said, adding it had received a letter from the group.
The group said in the letter, written in Swedish and posted on Wednesday, that Thursday's attack would be followed by others, Dagens Nyheter reported.
The newspaper quoted terrorism expert Magnus Norrell as saying that no similar attack has been committed in Sweden in Al-Qaida's name.
"It's the first of its kind," Norrel said.
Early Thursday, bottles of gasoline were thrown at a polling station in northern Stockholm as voters in Iraq and abroad began to elect the four-year term parliament. The bomb did not explode and nobody was injured.
The 40,000 Iraqi citizens living in Sweden are voting in the capital of Stockholm, and Goteborg in southwestern Sweden.
