An Afghan man was shot by police after two people were stabbed at the Amsterdam train station.
Police arrested the suspect after two people were wounded in what they said could be considered an extremist attack.
The 19-year-old man was questioned about his intention last night at the hospital where he was being treated for gunshot wounds while in custody, the Amsterdam city council said in a statement.
The people stabbed at the Central Station around noon were also treated in a hospital. His injuries were serious, but not life-threatening, according to the city statement. Neither they nor the suspect were identified.

"The victims were not chosen deliberately or with a clear reason," said the Amsterdam authorities.
"The investigation is still ongoing, and all the scenarios remain open for the research team."
The suspect has a German residence permit, and the Amsterdam police were in contact with the authorities in Germany to find out their background, according to the city government.
The stabbings occurred shortly after noon (1000 GMT, 6 a.m. EDT) at the Central Station in the center of Amsterdam when a man approached a group of people.
"Something happened, we still do not know what, but during those two people were stabbed and a person with a knife in his hand walked away and the police shot him," said police spokesman Rob van der Veen during the afternoon.
Forensic experts spent hours combing the scene, interrupting railway services until the rush hour in the afternoon.
Two platforms were temporarily closed for train traffic, but the station was not evacuated. Trams to and from the plaza in front of the station stopped when police and emergency services converged on the area. The red and white police tape kept members of the public away from the scene.
The Central Station is a busy entry and exit point for visitors to Amsterdam, with regular trains linking it to Schiphol Airport in the city. Friday is one of the busiest days of the week for train travel, as tourists arrive during the weekend.
"Something happened, we still do not know what, but during those two people were stabbed and a person with a knife in his hand walked away and the police shot him," said police spokesman Rob van der Veen.

The police, who shot and wounded a suspect, says the station has been evacuated and closed to all rail traffic
The police told the Dutch media that the aggressor's motive was unknown, and then tweeted that they were "looking at all the scenarios".
The police appealed for witnesses to appear.
The two injured people and the suspect with the knife were taken to the hospital, Amsterdam police said, although their status was not revealed.
A witness said he saw a young man & # 39; stumble & # 39; in his florist's shop at the station with a bleeding wound on his hand.
"Shortly after I heard some shots and I know something went wrong," Richard Snelders told the ANP news agency. A while later he saw another man lying on the ground nearby, he said.
"The first thing that comes up in your mind is that it's a terrorist attack – after all, you're at Amsterdam Central Station, there was a lot of panic," Snelders said.

Police quickly arrived on the scene and ordered one of the men in English to "stand still" after being shot, Snelders added. & # 39; It happened really fast & # 39;
The images published on social networks showed the security guards who took the passengers to the exits and the paramedics who arrived at the place with stretchers.
Initially, police said the station, located in the historic center of the Dutch capital, surrounded by canals, had been evacuated and closed to all rail traffic.
However, the police issued an update to say that "there was no talk" of a complete evacuation and that only two platforms had been closed for passengers.
An AFP correspondent at the scene said police cordoned off an area inside the station shortly after the incident and led crowds of people outside.
"A large group of people, including foreign tourists, still patiently wait outside the station," the correspondent said, adding that "there are still a large number of police present."
The two platforms that were cordoned off were reopened for rail traffic two hours later, police said.
Multiple police vehicles and ambulances were seen outside the large red brick station while security officers and police stood guard with high visibility vests.
The Netherlands has so far escaped the series of terrorist attacks that have shaken its closest European neighbors in recent years.
But in the midst of a series of scares and reports that people linked to some of the attacks may have briefly crossed the country, senior Dutch security and intelligence officials concerned have stressed that the level of threat is substantial.
Prime Minister Mark Rutte did not mention the incident at his weekly press conference.
Around 250,000 people travel through the Central Station every day, according to statistics provided by the Amsterdam.info travel guide.
The trams, which depart from the front of the station, were not working, police said, adding that there was no more information available immediately.
