Did an overnight Russian drone attack on May 13, 2023 in Khmelnytskyi, a city in the west of Ukraine, hit an ammunition storage facility that is supplied by NATO? No, that's not true: the drone attack hit infrastructure facilities. NATO stated, in an official response to the incident, that there is no ammunition storage supplied by NATO in Ukraine.
The claim in Romanian appeared in a video (archived here) that was published on TikTok by several users on May 14, 2023, under the title "Breaking news! The biggest explosion since the start of the war. Putin blew up a NATO ammunition depot 😂".
This is what the post looked like on TikTok at the time of writing:

On May 13, 2023, Russia sent 21 Iranian-made kamikaze Shahed drones, to attack cities across Ukraine overnight, according to Kyiv Independent, quoting Ukraine's air force Telegram channel. A drone attack hit infrastructure facilities in the city of Khmelnytskyi.
According to the Khmelnytskyi mayor, the attack left people injured and damaged residential and administrative buildings, as well as educational and medical institutions.
Romanian independent fact-checker Factual.ro asked NATO if there was such a thing as an ammunition depot supplied by the Alliance in Khmelnytskyi that would have been destroyed by a drone attack. NATO responded: "This is a completely false claim. NATO does not have troops nor equipment depots in Ukraine."
