A gunman wounded at least two people in the Netherlands in shootings that began at a house in the city of Rotterdam and continued in a classroom at a nearby medical centre.

Police said an arrest team had entered the medical facility in search of the suspect, described as a tall man in his mid-20s wearing combat fatigues. They said it was not clear whether he was still in the building.

Police confirmed two people were wounded, while Dutch press agency ANP, citing local authorities on the scene, said a third person had also been hurt. Reuters could not immediately confirm this.

Local safety authorities reported that there was also a fire at the house, which had since been put out.
