The militant group IS, according to Reuters, has taken responsibility for the attacks, which killed at least 128 people.
This morning, Swedish Intelligence Service (Säpo) had judged that there is currently no raised threat level against Sweden but they were continuing to follow developments in Paris.
However, the Paris attacks could indicate that it's time to change security work in the long run. Anders Kassman, chief of operations at Säpo, told Swedish Radio News that if IS has shifted its strategy to focus on Europe, this could change the way that European security services work.
Home Affairs Minister Anders Ygeman told Swedish Radio News on Saturday afternoon that the national center for terrorist threat assessment would meet today to review whether to raise the threat level in Sweden, but Ygeman said that the level probably won't change, because what happened in Paris already fits within the elevated threat level that Sweden has had since 2010.
And indeed, later in the afternoon, Anders Kassman, told TT that there was nothing to indicate that the terrorism threat level needed to be adjusted, based on the information that Säpo and the national center for terrorist threat assessment has. But he added that Sweden's current threat level does point out that there is a risk for a terrorist attack in Sweden.
"What could raise it is if we get to know about concrete plans of an attack in Sweden, and we are not there today," said Ygeman.
Meanwhile, the Swedish police are being extra vigilant throughout the country, Carolina Ekéus, press secretary at the police's Department of National Operations (NOA), told Swedish news agency TT.
She said that means police will be extra attentive to things that stick out.
Prime Minister Stefan Löfven called his security council to meet today at noon, according to Margot Wallström, Sweden's Foreign Minister at a press conference. She said that in part the meeting will be to keep an eye on the security situation in Sweden and also to talk about how Sweden can help France.
