A gunman has opened fire inside a tram in the Dutch city of Utrecht.
Several people have been injured and one is feared to have died in the shooting at about 10:45 local time (09:45 GMT) near the 24 Oktoberplein junction, reports say.
Police say the gunman is still at large. The area has been cordoned off, trams stopped and schools have been asked to keep their doors closed.
Counter-terror police reportedly say it has all the marks of a terror attack.
The Dutch anti-terrorism co-ordinator is in touch with local authorities and says the threat level has been temporarily raised to its highest point in Utrecht.
Prime Minister Mark Rutte said he was “deeply concerned” and cancelled his weekly coalition talks.
Security services have reportedly told Utrecht’s University Medical Centre to open the dedicated emergency ward to help care for the injured.
Utrecht University has reportedly closed all buildings, with nobody allowed in or out. Trains are also not allowed to run into Utrecht Central station.
“A man started shooting wildly,” one eyewitness told Dutch news site NU.nl.
Another witness told Dutch public broadcaster NOS he saw an injured woman with blood on her hands and clothes.
“I brought her into my car and helped her,” he said. “When the police arrived, she was unconscious.”
It is unknown how many were injured or how seriously they were hurt.
Utrecht’s transport authority said some tram services were again running in the city, although warned travellers to “take into account additional travel time”
