"Terrorists are very likely to try and carry out attacks in Sweden. Attacks could be indiscriminate, including in places frequented by foreigners," the ministry said.
There is overall a "heightened threat of terrorist attacks globally against UK interests and British nationals" emanating from "groups or individuals motivated by the conflict in Iraq and Syria," the statement read.
Swedish National Security Advisor Henrik Landerholm said the Swedish government and law enforcement bodies were monitoring the events and working with international partners to counter the spread of hate messages about Sweden.
On Thursday, Swedish police's chief of counterterrorism, Magnus Sjoberg, said that Sweden, along with Denmark and the Netherlands, has become a target of terrorist groups after it allowed demonstrations in its territory involving the burning of the Quran.
Several Quran-burning demonstrations have taken place in Denmark and Sweden in recent months. Most Muslim countries have condemned the demonstrations, and some have summoned the Swedish and Danish ambassadors to issue letters of protest.
