Video/ The chaos of the last few hours in Rotterdam. A boy walks into a hospital and kills people
The gunfire forced several patients and doctors to leave the Erasmus Medical Center in central Rotterdam, including some who were carried out of the building on beds.
Police Chief Fred Oesterbeke told reporters that the killer was a 32-year-old student from Rotterdam. He was arrested at the hospital at gunpoint. His identity has not been released and the motive for the shooting is still under investigation.
He first shot and killed a 39-year-old woman and seriously wounded her 14-year-old daughter in an apartment near where he lived. Police said the girl later died from her injuries.
The gunman then went to the nearby Erasmus Medical Center where he shot and killed a 46-year-old man, a professor at the academic hospital. He also exchanged fire with the police.
"It was a black day," said the mayor of Rotterdam, Ahmed Aboutaleb.
Dutch King Willem-Alexander and Queen Maxima expressed their grief on social media. "Our hearts go out to the family and friends of the victims of the violence this afternoon in Rotterdam," wrote the royal couple. "We also think of all those who have lived in fear during these terrible actions," they added.
Erasmus Medical Center appealed on social media for people not to go to the hospital, but later said it was reopening.
