'We don't know if Copenhagen shootings are linked' - police

A shooting near a synagogue in Copenhagen has left one person dead and two injured, hours after a deadly attack at a cafe in the city.

In the second shooting one person died after being shot in the head, and two police officers were wounded. The attacker is believed to have fled.

Earlier, a gunman killed one person and injured three at a free speech debate attended by a Swedish cartoonist.

Police spokesman Allan Wadsworth-Hansen said it was too early to say if there is was a definite link between two shootings.
