Zelenskiy vows to ‘liberate’ Crimea as Kyiv denies responsibility for deadly attack on Russian airbase in the annexed peninsula

A Russian airbase deep behind the frontline in Crimea has been damaged by several large explosions, killing at least one person. It was not immediately clear whether it had been targeted by a long-range Ukrainian missile strike. In his nightly address, Ukraine’s president, Volodymyr Zelenskiy, did not discuss who was behind the attacks but vowed to “liberate” Crimea, saying: “This Russian war against Ukraine and against the entire free Europe began with Crimea and must end with Crimea – with its liberation.” An adviser to the president, Mikhail Podolyak, said Ukraine was not taking responsibility for the explosions, suggesting partisans might have been involved.

The head of Ukraine’s state nuclear power firm warned of the “very high” risks from shelling at the Zaporizhzhia nuclear power plant in the Russian-occupied south and said it was vital Kyiv regains control over the facility in time for winter. Energoatom’s chief, Petro Kotin, told Reuters in an interview that last week’s Russian shelling had damaged three lines that connect the Zaporizhzhia plant to the Ukrainian grid and that Russia wanted to connect the facility to its grid.

Russian forces occupying the Zaporizhzhia nuclear plant are reorienting the plant’s electricity production to connect to Crimea, annexed by Moscow in 2014, according to Ukrainian operator Energoatom. “To do this, you must first damage the power lines of the plant connected to the Ukrainian energy system. From August 7 to 9, the Russians have already damaged three power lines. At the moment, the plant is operating with only one production line, which is an extremely dangerous way of working,” Energoatom president Petro Kotin told Ukrainian television. The plant, located not far from the Crimean peninsula, has six of Ukraine’s 15 reactors, and is capable of supplying power for four million homes.

Russia’s Baltic exclave of Kaliningrad has been struggling with quotas imposed by the EU for sanctioned goods that it can import across Lithuania from mainland Russia or Belarus, the region’s governor admitted. Lithuania infuriated Moscow in June by banning the land transit of goods such as concrete and steel to Kaliningrad after EU sanctions on them came into force, Reuters reported.

Russia has launched an Iranian satellite from Kazakhstan amid concerns it could be used for battlefield surveillance in Moscow’s invasion of Ukraine. Iran has denied that the Khayyam satellite, which was delivered into orbit onboard a Soyuz rocket launched from Baikonur cosmodrome, would ever be under Russian control. But the Washington Post previously reported that Moscow told Tehran it “plans to use the satellite for several months, or longer, to enhance its surveillance of military targets” in Ukraine, according to two US officials.
