Peace in Ukraine remains as elusive as when Russian tanks first streamed across its borders more than three years ago. This week’s talks in Istanbul—talks that Vladimir Putin himself proposed—show he isn’t yet ready to do a deal.

A Russian drone attack on a bus in northeastern Ukraine killed at least nine people and injured seven others, Ukrainian officials said Saturday, just hours after the two countries met for the first direct peace talk in three years.

Trump said he will speak to the Russian president, who recently skipped peace talks with Ukraine, on Monday morning.
