Sky News military analyst Sean Bell has been discussing the deadly Russian strikes on Ukrainian cities today.
"What we do know is that Russia is very short of missiles, as is Ukraine," he said.
"They want to use those missiles as effectively as they can do and we have seen Russia step up its attacks on, Ukraine's ability to generate weapons, its energy infrastructure and its airfields.
"And we don't know clearly - when these missiles get shot down by the Patriot missiles that are now in Ukraine... where the debris falls. Where the explosive actually explodes, we don't actually know, but it's very clear that Russia is trying to step up its efforts now.
"This is the summer offensive. If you remember, last year, you and I were talking about the Ukrainian spring offensive. That really fizzled out.
"And this year, because of the gap with the West supplying weapons, we fully expected Russia to launch its major summer offensive, We're midway through that [but] Russia is stalled on the front line, is suffering huge casualties, and I suspect this is a bit of an intensive effort in advance of the NATO summit. Just to demonstrate that Russia isn't finished just yet."
