It’s been a long time since Luhansk city was hit. It’s out of HIMARS range. And Ukraine hit it in the daytime for all to see.
“According to RU Rybar, Luhansk City was hit by what they claim is a cruise missile. This is very interesting because Luhansk functions as a large military base and logistics hub.”

“Three powerful arrivals at the Machine-Building Plant 100 in Luhansk. It sounded like rockets,” — russian media.”
