Sweden's Prime Minister Ulf Kristersson says the Nordic country intends to "intensify" border controls due to a worsened security situation in the wake of several protests involving desecrations of the Koran. Justice Minister Gunnar Strommer says the measure "enables us to identify incoming travellers that can threaten our security." Tensions have flared between Sweden and Muslim countries following several protests involving public desecrations of the Koran -- including setting pages alight.
