Police in Copenhagen say they have shot and killed a man who shot at them near a train station and are investigating whether he can be linked to two shootings hours earlier at a free speech event and at a synagogue.

A statement posted early Sunday by police says the shooting occurred after they had put an address near the train station under observation. The statement says no police officers were wounded.

The two earlier shootings left two dead and five police officers wounded, stirring fears that another terror spree was underway in a European capital a month after 17 people were killed in Paris attacks.
