Ukrainian President Volodymyr Zelenskyy visited troops at the front line near Bakhmut as Ukrainian forces continue to make ground in their counteroffensive, the president's office said Tuesday.

Zelenskyy, who was accompanied by commander of ground forces Col. Gen. Oleksandr Syrskyi, thanked soldiers for their service and presented them with awards, according to a video released by the office.

"I awarded the best warriors. And I thank everyone who fights for the sake of the state," Zelenskyy said.

Ukrainian defense forces continue to advance in the direction of Melitopol, according to the spokesman for Pavlo Kovalchuk, the general staff of the Armed Forces of Ukraine.

"They were successful in the direction of Robotyne - Novoprokopivka. They are entrenching at the achieved milestones," the spokesman said.

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.

Beginning in October, the U.S. will provide F-16 training to a small number of Ukrainian pilots and maintenance teams, Pentagon press secretary Brig. Gen. Pat Ryder said Thursday.

Ryder said "several" pilots and "dozens" of aircraft maintenance personnel will begin training at Morris Air National Guard Base in Tucson, Arizona, after they receive English training in September at Lackland AFB in San Antonio, Texas. The number of pilots and personnel will be determined by Ukraine.

"Although some Ukrainian pilots have English language skills we are anticipating that all the pilots coming to the United States will require some level of additional English language instruction, given the complexities and the specialized English that's required to fly these aircraft," said Ryder.

Sabrina Singh, the Pentagon's deputy press secretary, told reporters earlier this week that the U.S. was open to the idea of training on F-16's if European countries reached capacity though she couldn't define what numbers would constitute capacity. Ryder on Thursday also wouldn't provide a number and said the U.S. wasn't going to wait for the Netherlands and Denmark to reach capacity.

"We know that as the Danes and the Dutch prepare to train those pilots that at a certain point in time in the future, capacity will be reached. So preemptively acknowledging that and leaning forward in order to to assist with this effort is the impetus for why we're doing this now," said Ryder.

Ryder wouldn't get into when F-16 deliveries to Ukraine might begin. Denmark's Prime Minister said over the weekend that the first Danish F-16's could arrive by New Year's.
