Putin says he is ready to supply the EU with gas via Nord Stream 2; head of IAEA says morning power station outage caused by Russian shelling

Serhai Haidai, Ukraine’s governor of Luhansk, has posted an update on Telegram on Ukraine’s military progress in the occupied Luhansk region. He writes:

The armed forces of Ukraine are moving forward little by little. The Russians are shelling our positions mainly with rocket and barrel artillery. The occupiers are building a multi-layer defence line in Luhansk region, the entire first section of the front line is mined by them. Our military has already encountered the first wave of partially mobilised Russians.

The Federal Security Service, together with the Investigative Committee, established that the organiser of the terrorist attack on the Crimean Bridge was the Main Intelligence Directorate of the Ukrainian Defence Ministry, its head Kyrylo Budanov, employees and agents.

Currently, five citizens of Russia, three citizens of Ukraine and Armenia, who participated in the preparation of the crime, have been detained within the framework of the criminal case.

Despite – or because of – yesterday’s missile strikes on several Ukranian cities, people in Lviv, which was among the cities targeted by Russia, went dancing last night.

Wall Street Journal correspondent Matthew Luxmoore posted the below video on Twitter late on Monday night, adding that “Ukranian songs were interspersed tonight with chants of ‘Death to Enemies!’ and ‘Putin is a dick’!’”

Death toll from Monday’s strikes rises to 19 as Russian continues to attack Ukrainian cities with missiles; GCHQ boss says ‘No signs Russia is preparing to use nuclear weapon’

The death toll from Monday’s Russian missile attacks on a swathe of Ukrainian cities has risen to 19 people, with over 100 wounded, according to figures from the Ukrainian state emergency services.

Strikes continued on Tuesday. An attack on the Lviv region in western Ukraine on Tuesday left parts of the city without electricity. Governor Maksym Kozytskyi has said “At this moment, it is known about three explosions at two energy facilities in the Lviv region”. Mayor of the city, Andriy Sadovyi, appealed to residents to keep water supplies on hand ahead of expected service interruptions.

The Ladyzhyn thermal power plant (LTPP) in the Vinnytsia region was struck on Tuesday morning. Regional head Serhiy Borzov said: “An attack was launched on the LTPP. Two Shahed-136 kamikaze drones.”

There has been a lengthy air raid warning in place all morning in Kyiv, with governor Oleksiy Kuleba claiming that at least one rocket had been shot down.

Valentyn Reznichenko, the governor of Dnipro, has claimed that air defence systems had shot down four missiles over the region. Vitaliy Kim, the governor of Mykolaiv, has said that “there are still missiles in the air” and that Ukraine’s air defences continue to work.

The head of GCHQ has said the UK spy agency has not seen any indicators that Russia is preparing to use a tactical nuclear weapon in or around Ukraine despite recent bellicose statements from Vladimir Putin. Jeremy Fleming, speaking on Tuesday morning, said it was one of GCHQ’s tasks to monitor whether the Kremlin was taking any of the preliminary steps needed before a tactical weapon was being made ready.

Fleming is expected to say in a rare public speech delivered later on Tuesday that Putin is making strategic errors due to unconstrained power. “Far from the inevitable Russian military victory that their propaganda machine spouted, it’s clear that Ukraine’s courageous action on the battlefield and in cyberspace is turning the tide,” Fleming will say. “With little effective internal challenge, Putin’s decision-making has proved flawed”

Meanwhile, a series of images shared by Zaporizhzhia’s administrative head Anatoly Kurtev shows the aftermath of the overnight missile attack.

A series of blasts have rocked Ukraine’s capital of Kyiv, according to local media reports and regional officials.

Series of missiles shatter several months of calm but normal life quickly returns amid the destruction

• Russia-Ukraine war – latest updates

Shevchenko Park in central Kyiv is a tranquil public garden, where the trees are turning golden against the city’s blue, autumnal skies. Presiding over the park is a statue of Taras Shevchenko, Ukraine’s national poet, persecuted by the Russians in the 19th century for writing in Ukrainian.

But on Monday that sense of calm was violently shattered when a series of missiles hit the city centre. War had returned to what had been, for several months, a mostly peaceful – if anxious – city.
