Russia has named a new acting head of its aerospace forces to replace General Sergei Surovikin, who disappeared after a brief mutiny by Wagner's mercenaries against the top in June, state news agency RIA reported on Wednesday.
During the rebellion of 23-24. In June, Surovikin, who once commanded Russia's overall war effort in Ukraine - what Moscow calls a "special military operation" - appeared in an unmarked video calling on the leader of Wagner's mercenaries, Yevgeny Prigozhin, to step down, Reuters reports.
Since the rebellion, which ended in a negotiated settlement, unconfirmed Russian and foreign news reports have reported that Surovikin is being investigated for possible complicity in the rebellion and is being held under house arrest.
"The former head of the Russian Aerospace Forces, Sergei Surovikin, has now been relieved of his duties, while Lieutenant General Viktor Afzalov, the Chief of the General Staff of the Air Force, is temporarily the acting Commander-in-Chief of the Air Force. Force," an unnamed source told RIA.
Surovikin earned the nickname "General Armageddon" during the Russian military intervention in Syria.

The Russian Ministry of Defense announced that air defense forces shot down two drones near the capital over Mozhai and Khimki districts in the Moscow region.
A third were said to have become stuck and lost control - but still crashed into a high-rise building under construction in Moscow's business district. The same district, known as Moscow City, was hit twice in three days at the beginning of the month, reports Reuters.

The state news agency TASS reported that the glass panels on three floors of the multi-story building were damaged. Unverified videos on social media show less damage than the other two drones that were destroyed.

Russia targeted Ukrainian ports in the southern Odesa region and the Danube River area in drone strikes overnight, setting fire to at least one grain warehouse, Ukraine's military and local authorities said Wednesday.
The attacks were the latest Russian attacks on port infrastructure on the Danube, which Ukraine uses to transport grain to the Romanian port of Constanta, since Moscow abandoned a UN-brokered deal that allowed Kiev to ship grain across the Black Sea, Reuters reports.
"The enemy hit grain warehouses and a production and transshipment complex in the Danube region. A fire broke out in the warehouses and was quickly contained. Firefighters continue to work," the Ukrainian military said in a post on the Telegram messaging app.
The army released photos showing piles of grain under a burned and shattered shell warehouse.
Odesa Governor Oleh Kiper said the attack on the region lasted three hours and that the Ukrainian Air Force destroyed nine Russian drones.
"Unfortunately, there were hits in the production and transshipment complexes where the fire broke out... The damage also includes grain warehouses," Kiper said on Telegram.
Ukraine's air defenses said later Wednesday that they had shot down 11 of 20 drones launched by Russia overnight.
An industry source told Reuters that Ukrainian ports on the Danube were the main targets. Ukraine manages two large ports on the Danube - Izmail and Reni.
Danube ports accounted for about a quarter of Ukraine's grain exports before Russia pulled out of an agreement in July to provide safe passage for Ukrainian grain exports across the Black Sea.
The ports have since become the main outlet, and grain is also sent by barge to the Romanian Black Sea port of Constanța for onward shipment.
Global grain prices rose earlier this month, when Russia attacked Izmail - Ukraine's main inland port across the Danube from Romania and the Reni port.
Russian authorities said Tuesday evening that they had sent two planes to intercept two unmanned aerial vehicles, the MK-9 Ripper and the Bajraktar TB2, over the Black Sea, without specifying whose drones they were.
"Two Russian planes were sent to prevent a possible violation of Russia's border and to block the drone's electronic guidance mission," said the Ministry of Defense there.
It is added that after that the drones changed their path and left the air zone in which they were located.
