Ukrainian President Volodymyr Zelenskiy received a report from his intelligence director on August 1, a day marked by air-raid alerts across the country and drone attacks on the Crimean Peninsula and Moscow.
"The occupiers will definitely feel the consequences of our work. They will seriously feel it," Zelenskiy said in a video on Facebook after a closed-door meeting with Kyrylo Budanov, chief of the Intelligence Directorate of Ukraine's Defense Ministry.
Zelenskiy did not provide further details about what was discussed with Budanov during the morning meeting that also included the heads of law enforcement and military agencies.
A Russian missile attack during the day hit a hospital in Kherson, killing a doctor and injuring several medical workers, regional officials said.
Military administration head Roman Mrochko said the doctor had worked in his position for only a few days. Several other medical workers were injured in the attack, including a nurse who suffered serious injuries.
The reports could not be immediately verified.

"We unequivocally condemn this disgraceful attack on a medical facility and extend our condolences to the family of the doctor who died," MSF said on social media.
Russian troops shell Kherson and the liberated part of the region almost every day. Despite the evidence and testimony to the contrary, Moscow has denied targeting civilians since the beginning of the full-scale invasion more than 17 months ago.
In a separate incident in a northeastern village, an elderly woman was killed and a man was wounded in Russian shelling on August 1, Kharkiv regional Governor Oleh Synehubov said on Telegram.
The second air-raid alert declared for Kyiv and most of Ukraine came just hours after a first alert that followed a Russian drone strike that destroyed a college dormitory in Ukraine's eastern city of Kharkiv.
Authorities said the alert was prompted by the heightened likelihood of Russian drone and missile strikes after Ukraine's General Staff said early on August 1 that Russian forces carried out nine missile and 57 air strikes on Ukraine over the previous 24 hours.

At least one person was wounded in the attack on Kharkiv, which Mayor Ihor Terekhov said targeted the city's densely populated suburbs and involved at least three drones.
"One of the drones destroyed two floors of one of the dormitories," Terekhov said.
Deputy regional Governor Yevhen Ivanov said the most recent attacks were the first time that Kharkiv, which is close to the border with Russia, was struck by drones.
In Moscow, Mayor Sergei Sobyanin said the Russian capital repelled a Ukrainian drone attack early on August 1 but one office tower was damaged, while one of the city's main airports was briefly closed.
"Several drones were downed by air-defense systems while attempting to reach Moscow. One hit the same tower in the city as last time," Sobyanin wrote on Telegram, referring to the building that was struck in a previous drone attack over the weekend.
Sobyanin said the drone attack didn't cause any casualties. Russian authorities accused Kyiv of staging the attack. Ukrainian presidential adviser Mykhaylo Podolyak said that Moscow "is rapidly getting used to a full-fledged war,'" without confirming or denying Kyiv’s involvement.
The office building complex, located about 7 kilometers from the Kremlin, is the headquarters of a number of government agencies, including the Ministry of Economic Development, the Ministry of Digital Development and Communications, and the Ministry of Industry and Trade.
It wasn't clear why the same building was hit twice in a row. In both incidents, the Russian military said the drones that hit the skyscraper were jammed before crashing.
Oleksiy Danilov, secretary of the National Security and Defense Council, said Ukraine had the right to use weapons manufactured domestically wherever the country's military considers it necessary.
It is not worth thinking that "combat actions will take place only on our land," he said on Ukrainian television. "Everything related to Moscow, the city where the decision to kill our citizens is made, should simply cease to exist."
Explosions were heard later on August 1 in the port city of Sevastopol in the Russian-occupied Ukrainian region of Crimea. Explosions are heard almost daily in the region, which Russia illegally seized in 2014.
Mikhail Razvozhayev, the Moscow-installed administrator of Sevastopol, said a drone was shot down, causing an explosion on the ground and some bushes to catch fire.
In the eastern region of Donetsk, two civilians were killed by Russian shelling over the past 24 hours, regional Governor Pavlo Kyrylenko said on Telegram on August 1.
On the battlefield, Ukrainian forces have been engaged in heavy fighting along the entire front line, fighting more than 40 close-combat battles over the past day, the General Staff of Ukraine's military said in its daily report on August 1.
The British Ministry of Defense, in its daily intelligence bulletin, reported "intense fighting" in southern Ukraine.
Russia's Defense Ministry said on August 1 that Valery Gerasimov, chief of the General Staff of Russia's armed forces, had visited Russian troops in Ukraine's southern region of Zaporizhzhya.
The previous day, Deputy Ukrainian Defense Minister Hanna Malyar reported advances in the counteroffensive in Zaporizhzhya.
"We are gradually but surely moving [ahead] in the Berdyansk and Melitopol directions," Malyar said on Telegram, adding, "Fighting continues in all directions of the counteroffensive."
Separately, Russia on August 1 said it had repelled an overnight attack by Ukrainian naval drones that targeted its patrol boats in the Black Sea.
"During the night, Ukrainian armed forces tried without success to attack with three drones the Sergei Kotov and Vasily Bykov, patrol boats of the Russian fleet in the Black Sea," the Defense Ministry said in a statement, adding that the drones were destroyed some 340 kilometers southwest of Sevastopol, the port that houses Russia's Black Sea Fleet on the occupied Crimea Peninsula.
The claim could not be independently verified.
Tensions in the Black Sea have been on the rise since Russia refused to extend a Turkey- and UN-sponsored deal that had made possible the safe export of Ukrainian grain by sea.
