Vladimir Putin said Ukraine must surrender after President Donald Trump urged the Russian leader to spare the lives of Ukrainian soldiers, following ceasefire talks between the U.S. and Russia in Moscow.

Russian President Vladimir Putin has called on Ukrainian troops in the Russian region of Kursk to surrender, as diplomatic back-and-forth continues over a potential US-brokered ceasefire with Ukraine.

Despite flirting with Trump there is little evidence Putin has shifted from his core war goals: cementing his landgrabs in Ukraine and stopping it joining NATO.
