It seems clear that the Russian strategy is to terrorise the residents of Irpin into submission and empty the city - a tactic Moscow has used elsewhere from Grozny to Aleppo. The residents who remain have endured days and nights of relentless bombardment. We could hear the assault during an earlier visit on Saturday. The soundtrack was the same today, except maybe louder. And this time we could also hear grad rocket fire, and occasional gunshots.
