A Soviet-era "Fagot" anti-tank missile system was discovered in a forest near J贸zef贸w, Warsaw agglomeration, on September 15th, 2025. The discovery was reported via social media by Militarnyi. Separately, an anonymous post on X claimed an attack on the ROSATOM nuclear power plant, stating the group possesses "secret information of nuclear weapons and waste." The discovery of the Fagot system, an anti-tank guided missile, was made within the past 15 minutes, according to Militarnyi's reporting. The specific circumstances of its abandonment and presence in the forest are currently unknown. The anonymous claim regarding ROSATOM was posted approximately 15 minutes prior to this report, at 8:02 PM UTC, and included a cryptocurrency ticker. This activity follows a previous incident earlier on September 15th, 2025, where Polish security forces neutralized a drone over government buildings and the Belweder Palace in Warsaw, leading to the detention of two Belarusian nationals. Prime Minister Donald Tusk confirmed the drone incident, stating that police were investigating. The previous report indicated the drone neutralization occurred around 6:30 PM UTC, with confirmation at 6:19 PM UTC.
