The mayor of the Dutch city of Utrecht says three people have died after a shooting on a tram.
Nine people have also been injured.
The incident happened in the city, 45 minutes south of Amsterdam, this morning.
The country's Prime Minister says authorities are focused on catching the "suspect or suspects".
Police have tweeted a photo of one suspect they are looking for - 37 year old Turkish-born Gokman Tanis.
An apartment near the tram is currently surrounded by police.
Sky's Enda Brady says, "What we don't know yet is whether the gunman or gunmen fired from inside the carriage of the tram, or whether they were on a platform or on the street. That detail hasn't emerged yet."
Security expert, Renske Van Der Veer, says a terrorist motive is being explored:
"The Dutch Coordinator for Security and Counter Terrorism has indeed raised the threat level to a number 5 [the highest possible level], which is unheard of in the Netherlands, it has never happened before.
There really is a current and actual threat."
