In extraordinary video tirade, Yevgeny Prigozhin attacks defence minister and chief of armed forces

• Russia-Ukraine war – latest news updates

The leader of the Wagner mercenary group has brought escalating tensions with the Kremlin military leadership dramatically into the open after he recorded an expletive-ridden video in a field littered with corpses and blamed Russia’s top defence chiefs for the losses.

“These are Wagner lads who died today. The blood is still fresh,” Yevgeny Prigozhin says in the extraordinary clip, pointing to roughly three-dozen bodies that he says are those of the Wagner fighters. “They came here as volunteers and are dying so you can sit like fat cats in your luxury offices.”

Here is more on the oil refinery attack from Tass and Reuters.

Part of an oil refinery in southern Russia is on fire after it was hit by a drone attack, Tass news agency cited local emergency services as saying early on Thursday.

Tass said the incident occurred at the Ilsky refinery near the Black Sea port of Novorossiysk. It cited a source as saying a fuel reservoir was on fire but gave no details.

Ukraine rarely claims responsibility for what Moscow says are frequent drone strikes against infrastructure and military targets, particularly in regions close to Russia.

Last June the Novoshakhtinsk oil refinery in Russia’s Rostov region, bordering Ukraine, suspended operations after two unmanned aerial vehicles attacked its facilities.

Strikes kill total of 16 and come after leak suggested Ukraine air defence missiles would run out this week

• Russia-Ukraine war – latest news updates

Russia has launched a wave of missile and drone attacks on Ukraine, killing 16 as Moscow tested the strength of the country’s air defences in intensified fighting, including eight people after hitting a supermarket in the southern city of Kherson.

The strikes early on Wednesday, the latest in a string of attacks over the last week, come after leaked Pentagon documents suggested Ukraine would run out of missiles for its S-300 primary air defence system on Tuesday unless Kyiv could urgently find replacements.

Russia has claimed that the Black Sea grain initiative has not allowed it to export agricultural products. State-owned news agency Tass outlines this morning what Russia is looking to achieve with any extension of the deal. It writes:

The Russian foreign ministry indicated that a further decision to extend the deal would depend on the reconnection of Rosselkhozbank [Russian state-owned agricultural bank] to the Swift payment system, the resumption of supplies of agricultural machinery, spare parts and services, the lifting of restrictions on insurance and reinsurance, the lifting of the ban on access to ports, the resumption of operation of the Togliatti-Odesa ammonia pipeline, [and] unblocking foreign assets and accounts of Russian companies associated with the production and transportation of food and fertilisers.

During the meeting, some issues starting with the grain initiative will be discussed. In this regard, we can say that the sides are looking warmly at the extension of the duration. Our wish is that this initiative is extended without any trouble.
