Three people were killed and one seriously injured in a shooting in the Dutch city of Dordrecht on Monday.
Police officers and emergency services were filmed from the other side of a cordon.
Mayor of Dordrecht Wouter Kloff, who was present on site, said that "the impact as you can imagine is very heavy. Everyone in this neighbourhood knows each other, children play together, as you can imagine, this is very terrible."
Dutch media have reported the incident as a family shooting, involving two children. This has not yet been officially confirmed. An investigation is however underway, according to a tweet from the Rotterdam police.
