Two women have died in a knife attack on Thursday at a shopping center in the Hradec Králové, officials said.

Police say they detained a teenage suspect in connection with the stabbings in a store in the city of Hradec Kralove, some 100 east of Prague.

Reports initially said the victims had been injured, one of them seriously, but police later said both had died. They were not identified.

A 16-year-old Czech national was detained by police about one 1 kilometer from the scene, shortly after the attack. A knife was found nearby.

Prime Minister Petr Fiala offered his condolences to the relatives of the dead.

“What has happened in Hradec Kralove today is an absolutely incomprehensible and horrible act,” he posted on X.

Police say the situation was under control and there was no danger to the public. No other details were immediately available.

The store was surrounded by police tape, but according to local reporters, the shopping area is still in normal operation.

“We are investigating the attacker’s motivation through the National Center for Combating Terrorism, Extremism and Cybercrime and other analysts. As soon as we have the initial information, we will publish it,” police officers added on X.
