Russia-Ukraine updates: Russian missile strikes hit multiple Ukrainian cities

Cuban officials announced Monday that they have "detected" and are "working on the neutralization and dismantling of a human trafficking network that operates from Russia to incorporate Cuban citizens living there, and even some from Cuba, into the military forces participating in war operations in Ukraine."

"Attempts of this nature have been neutralized and criminal proceedings have been initiated against people involved in these activities," the Cuban Ministry of Foreign Affairs said in a statement.

The ministry noted that "Cuba has a firm and clear historical position against mercenarism and plays an active role in the United Nations in repudiation of this practice."

"Cuba is not part of the war in Ukraine," the ministry added. "It is acting and will act energetically against anyone, from the national territory, who participates in any form of human trafficking for the purpose of recruitment or mercenarism for Cuban citizens to use arms against any country."

Russian officials are claiming a drone attack on the Bryansk region by Ukraine, the second such attack in the country in as many nights. Two drones were allegedly shot down by air defense in the city, according to local officials.

One of the Ukrainian kamikaze drones that attacked Bryansk fell on the hotel of the Department of Affairs of the regional government, about 100 meters from the building of the regional administration, according to multiple local officials.

Meanwhile, Russia claimed it repelled a drone attack on the Moscow region. The drone attack Thursday morning caused no casualties or destruction in the Voskresensk district of the Moscow region, the district's head, Alexei Malkin, said.

"No traces of destruction have been discovered thus far. No one was injured. All emergency services are working at the scene," Malkin said on his Telegram channel.

"On-duty air defenses destroyed the unmanned aerial vehicle over the Voskresensk district of the Moscow region," the ministry said.

The Kremlin on Wednesday acknowledged for the first time that a plane carrying Yevgeny Prigozhin, mercenary chief of the paramilitary Wagner Group, was possibly downed on purpose.

Kremlin spokesman Dmitry Peskov told reporters that investigators are looking into the possibility that the 62-year-old Prigozhin was assassinated.

"It is obvious that different versions are being considered, including the version -- you know what we are talking about -- let's say, a deliberate atrocity," Peskov said when asked about the investigation.

The plane carrying Prigozhin and nine others crashed in Russia's Tver region on Aug. 23, killing everyone aboard, according to the press service of Russia's Federal Air Transport Agency.

The crash came about a month after Prigozhin led a chaotic armed rebellion that threatened the longstanding leadership of Russian President Vladimir Putin.

On Friday, Peskov denied speculation that the Kremlin was involved in the plane crash, calling the allegation an "absolute lie."

The crash investigation is being conducted by the Russian Investigative Committee as a domestic incident and Peskov said that allowing in international investigators "is out of the question."
