Is Russia Punishing Kharkiv for Resisting? "Brutal Assault" Reduces Homes & Schools to Rubble

Ukrainian and Russian officials have begun a new round of peace talks in Istanbul, Turkey. Meanwhile, U.N. Secretary-General Antonio Guterres called for a humanitarian ceasefire to end the war, which began when Russia invaded Ukraine 34 days ago. The Guardian's Emma Graham-Harrison speaks to us from Lviv, just back from reporting in bombed-out Kharkiv, one of Ukraine's largest cities bordering Russia, where Putin's army has launched one of its most brutal coordinated attacks. Graham-Harrison describes how the Russian military is pummeling" civilian neighborhoods because they have not yet been able to take over Kharkiv.
