UPDATE 1-Danish police carry out nationwide raids over suspected attack preparations

Police made several raids throughout Denmark on Wednesday and arrested a number of people in connection with suspected preparations for an Islamist militant attack, police said.

Police and intelligence services will hold a joint news conference at 1600 GMT to give more details. Denmark has not seen a militant attack since 2015 when two people were killed and six police officers were wounded.

In that incident, a lone gunman shot and killed a man outside a culture center hosting a debate on freedom of speech, and later killed a person outside a Jewish synagogue in central Copenhagen. The gunman was killed in a shoot-out with police. This year, the Danish government-imposed temporary border controls at its border with Sweden following the bombing of the Danish Tax Agency in Copenhagen, which led to the arrest of three Swedish men.
