Poland launched on Monday an investigation into a fire at a drone production factory south of Warsaw, suspecting terrorism and the involvement of a foreign intelligence service.

The prosecution said the probe is looking into the possible "participation in the activities of a foreign intelligence service directed against the Republic of Poland and for a terrorist offence, consisting of deliberately causing a fire on the premises of the WB Electronics factory using a device containing flammable materials."

A fire was reported at the WB Electronics factory in Skarzysko-Kamienna, located 150 kilometers south of Warsaw, shortly after midnight on Monday. The facility manufactures key components for drones.

Firefighters spent two hours containing the fire. There were no injuries in the incident.

Poland's Internal Security Agency (ABW) is assisting the police with the investigation, officials said.

Poland supports Ukraine in its war with Russia

Earlier, the Polish government accused Russia and Belarus of sending several agents into the country to carry out acts of sabotage.

Poland, who has been a vocal supporter of Ukraine since Russia's full-scale invasion into the country, has been increasing its security expenditure and military capabilities due to fears of Russian attacks.

WB Electronics, Poland's largest private defense company, is a supplier to the Polish military. 

The company specializes in developing and manufacturing advanced defense technologies, including digital command and control systems, automated fire control systems, communications equipment, and modern unmanned strike systems.
