A man stabbed and injured three people in the centre of The Hague on Friday, Dutch police said on Twitter.
Medical response officials rushed to the scene at the Grote Marktstraat, a busy shopping street in the city centre, the ANP news agency reported.
According to the police, they were searching for a man between the ages of 45 and 50. The background to the incident was initially unclear.
The incident occurred just hours after a terrorist attack in London where two people were killed and three others injured in a knife attack. The alleged perpetrator was shot dead by police after a scuffle with passers-by.
The male suspect was wearing a "hoax explosive device," said Neil Basu, the head of Britain's counterterrorism policing.
