Yevgeny Balitsky, the head of the Russian-imposed administration of the occupied Zaporizhzhia region of Ukraine, has described the situation on the frontline there as “tense”.

Very little reliable detail is emerging from the active combat zones. Balitsky claims that Russian forces control the Vremivka direction, which is just over the regional border from Zaporizhzhia into Donetsk.

The night was quiet. There was little activity of enemy aircraft. There are not many nights like this. Many Ukrainians had the opportunity to sleep at least. We hope this day will be calm, but according to the general staff there is still a high probability of missile attacks. Therefore, we all need to be vigilant and respond to the messages we receive about air threats every time.

Pavlo Kyrylenko, Ukraine’s governor of Donetsk, has given civilian casualtiy figures in the Ukraine-controlled portion of the region. On Telegram he stated that in the last 24 hours one person was killed and nine injured.

The claims have not been independently verified.

The losses from Ukraine’s much vaunted counteroffensive were heavy and early. Pushing into the country’s sprawling southern fields earlier this summer, Kyiv lost almost a fifth of Nato kit provided for the operation, according to Ukrainian and western officials.

Kyiv’s military response across much of the frontline is now becoming clear: to change tactics. The shift in fighting doctrine applied in recent weeks, according to Ukrainian commanders, appears to be achieving some hard-fought but tangible results on the battlefield, at a more tolerable cost.

It makes moral and economic sense for west to help more as Kyiv cannot protect all main cities, aide says

Ukraine cannot protect all of its main cities from Russian missile threats without a significant increase in the provision of air defence systems, according to a key adviser to President Volodymyr Zelenskiy.

Mykhailo Podolyak said the strikes on Odesa over the past week had shown clearly that the Russian strategy was to bombard Ukrainian cities, with the aim of overwhelming air defence systems.

The UK Ministry of Defence has issued its daily intelligence briefing on how it sees the war progressing, and today the focus is on Odesa. The ministry writes that since 18 July 2023, Russia has conducted greater numbers of long-range strikes against Odesa, and puts this down to the end of the Black Sea grain deal.

It says:

Between August 2022 and June 2023, when the Black Sea Grain Initiative was still in force, Russia generally refrained from striking civil infrastructure in the southern ports.

Since Russia failed to renew the deal, the Kremlin likely feels less politically constrained, and is attempting to strike targets in Odesa because it believes Ukraine is storing military assets in these areas.

Russia’s overnight drone attack on the southern Ukrainian port of Odesa destroyed a grains depot and injured four port employees, Reuters reports Ukraine’s southern military command as saying.

Based on preliminary information, three drones were destroyed in the attacks, the command said on social media.

These are still relatively early days of the counteroffensive. It is tough.

It will not play out over the next week or two. We’re still looking, I think, at several months.

And the important focus is on making sure that when they do, they’re properly trained, they’re able to maintain the planes, and use them in a smart way.

A new wave of Russian strikes on Odesa have killed one person and damaged a historic cathedral, as missiles again rained down on the southern Ukrainian city.

Authorities said 22 people were injured in the attacks in the early hours of Sunday, including a number of children. One strike hit the Transfiguration Cathedral, which was built in the late 18th century, destroyed under Joseph Stalin and then rebuilt in the early 2000s.
