French President Emmanuel Macron and German Chancellor Olaf Scholz urged Russian President Vladimir Putin on Saturday to release the 2,500 Ukrainian defenders of the Azovstal steel plant detained by Russian forces, the Elysee palace said.
The two European leaders, in a joint call, also urged Putin to accept a direct exchange with Ukrainian President Volodymyr Zelenskiy, the palace said.
Russia said this month that almost 2,000 Ukrainians had surrendered after making a last stand in the ruins of Mariupol, where they had held out for weeks in bunkers and tunnels beneath the vast Azovstal steelworks.
Macron and Scholz also insisted on the urgency of lifting the Russian blockade of the port of Odesa to allow Ukrainian grain exports, the palace said.
The Kremlin said Putin told Macron and Scholz in the call that Russia was willing to discuss ways to make it possible for Ukraine to resume shipments of grain from Black Sea ports.
Russia invaded Ukraine on Feb. 24 in what it called a "special operation" to demilitarise and "denazify" its southern neighbour. Ukraine and Western nations have dismissed this as a baseless pretext for war.
