Blow for Putin as Bulgaria aims to seize control of Russian oil refinery
Putin orders nuclear weapons test preparations after Trump threat in new escalation
Bulgaria is drafting new legislation to seize control of the Burgas oil refinery, its only such facility, which is owned by Russia's sanctioned oil giant Lukoil.
Lukoil is currently facing US sanctions due to Russia's war on Ukraine, impacting its foreign business operations.
Russian President Vladimir Putin ordered preparations for nuclear weapons testing after president Donald Trump announced the US would conduct its first tests in over three decades.
Putin also mandated heightened defence of Russia's oil refineries from Ukrainian drone attacks, deploying millions of reservists for this purpose.
On the battlefield, Russia claimed its troops were advancing in the key Ukrainian city of Pokrovsk, where Ukrainian forces are battling to avoid encirclement.
