The cause of the explosion at the Oktyabrskaya station was not immediately clear, dpa reported.
Witnesses told the Belapan news agency that black smoke could be seen rising from the underground. Hundreds of people evacuated the station after the explosion, which took place at the height of rush hour.
Ambulances and firefighters were on the scene as well police, who were cordoning off the blast site.
Medics were treating some victims outside the metro entrance, web photographs showed.
A video posted on the internet only minutes after the explosion showed a man and a woman within the metro station being treated to the hand and leg.
Twitter reports from persons saying they were there at the time of the explosion were conflicting, with some saying the explosion took place aboard a train passing through Oktiabrsky Station, and others describing the blast as within the station itself.
The explosion took place at a central station connecting two metro lines in the Belarusian capital. The station is located near the residence of President Aleksander Lukashenko.
Traffic was interrupted at one line and proceeding normally on the other, according to reports.
