Russia about to run out of steam in Ukraine, British spy chief says

Russia's military is likely to start an operational pause of some kind in Ukraine in the coming weeks, giving Kyiv a key opportunity to strike back, Britain's spy chief said on Thursday, addressing the Aspen Security Forum in Colorado.

"I think they're about to run out of steam. I think our assessment is that the Russians will increasingly find it difficult to supply manpower material over the next few weeks," said Richard Moore, chief of the Secret Intelligence Service (SIS) known as MI6.

"They will have to pause in some way, and that will give the Ukrainians opportunities to strike back."
