TRELLEBORG: At least half a dozen people were injured after gunshots rang out late Thursday night in a busy market here in Sweden's southern town, reports from international media outlets indicated.

Multiple people were wounded in firing "incidents" in the heart of the Scanian town, British media outlet Express UK said.

Shortly thereafter, armed police arrived and cordoned off the crime scene, where witnesses had reported hearing a loud "bang".

A police spokesman explained that after receiving "several reports of a shooting", law enforcement authorities "found that, within a fairly limited area, we find more people with suspected shot injury", according to the publication.

With "a major police operation" being carried out in ?multiple locations?, security officials have blocked some areas and are conducting "an investigation".

There is no official word yet from the authorities regarding either the suspect or the victims.

It is unconfirmed at present whether there is more than one shooter or if anyone has been detained.

The victims' condition, on the other hand, also remains unknown.
