A Telegram channel reported that 6-8 S-400 missiles were preliminarily used against Kyiv, with no prior information about launches. It is currently unknown if the lack of normal detection is linked to alleged US threats to cease providing intelligence data, as reported by media.

The source also noted that there was no information about the launches beforehand. Media reports indicated potential US threats to stop providing intelligence data, but a connection to the current situation is unconfirmed.
