Shortly after a gunman killed one person and injured three policemen at a free speech debate in Copenhagen, another person was reportedly shot in the head and two cops were injured in another attack that took place at a synagogue, just two miles away from the earlier incident.
A train station near the synagogue has been shut down and evacuated after the attack, reported The Mirror.
Police said that it was unclear if the two incidents were related.
Earlier, several rounds of shots were fired at a free speech debate attended by Swedish cartoonist Lars Vilks.
Vilks escaped unharmed and said that he believed that he was the "intended target."
A manhunt has been launched to nab the gunman.
