Ukraine and Russia exchange drone attacks on energy infrastructure

Ukraine and Russia are attacking each other's energy infrastructure with drones. Ukraine's president, Volodymyr Zelenskyy, said there is no formal deal, but Ukraine would hold fire on energy targets if Russia does the same.

Russia's attacks have caused an energy emergency in Ukraine during winter, while Ukrainian drone strikes have caused fires at Russian oil refineries and a depot. The attacks have also affected Kazakhstan's oil output.
