At least four people have been killed in Crimea, Moscow-installed authorities said on Thursday, a day after Kyiv targeted energy and military facilities in Saint Petersburg during Russia's flagship economic forum. US Secretary of State Marco Rubio warned of a "real" risk of escalation, while Ukraine described the attacks as justified retaliation for intensified Russian strikes on its territory.
Sergei Aksyonov, the Russia-appointed head of Crimea, said Ukrainian forces had hit a non-residential part of Simferopol, the peninsula’s main administrative town, killing three people and injuring seven.
