Russia-Ukraine Crisis: Ukraine ruled out a ceasefire or any territorial concessions to Russia, according to reports, and Poland’s president said any loss of Ukrainian territory would be a “huge blow” to the entire West as he warned against appeasing Russian President Vladimir Putin. The Russian-appointed head of the occupied Ukrainian town adjacent to the largest nuclear power plant in Europe was injured in a blast on Sunday.

Andrei Shevchik, named mayor of Enerhodar by Russia, was in intensive care following the explosion. With Russia claiming to have taken prisoner nearly 2,500 Ukrainian fighters from the besieged Mariupol steel plant, concerns grew about their fate as a Moscow-backed separatist leader vowed they would face tribunals.

Russia has declared its full control of the Azovstal steel plant, which for weeks was the last holdout in Mariupol and a symbol of Ukrainian tenacity in the strategic port city, now in ruins with more than 20,000 residents feared dead.

Russian gas producer Gazprom said it continues to supply gas to Europe through Ukraine via the Sudzha entry point, with volumes on Sunday seen at 44.7 million cubic metres (mcm) down from 45.9 mcm on Saturday.
