The Ukrainian military has said it has killed another senior Russian officer with the rank of general.
The commander of the 1st army corps of the separatist Donetsk People's Republic, Major General Roman Kutuzov, had been "officially denazified and demilitarized", the administration for strategic communications of the Ukrainian armed forces said on Monday night, according to the online portal "Ukrainskaya Pravda".
A correspondent for Russian state television first reported on Kutuzov's death.
Kutuzov is said to have fallen while leading a Russian attack on a town near Popasna in the Luhansk Oblast in eastern Ukraine.
The Ukrainian side had previously reported that the Russian attack had been repelled and that the enemy had been forced to withdraw with "significant casualties".
Since the start of Russia's war of aggression against Ukraine on February 24, several Moscow generals have been killed.
Official Russian sources, meanwhile, have confirmed the deaths of four generals.
Ukraine had even spoken of at least seven Russian generals killed.
However, two of them turned up alive after the Ukrainian death report.
Warning of new attacks on Kyiv
The Ministry of Defense in Kyiv warned of the danger of new attacks after the first rocket attacks on the Ukrainian capital since the end of April.
"We have always said openly that Kyiv is constantly under threat," Deputy Defense Minister Hanna Maljar said on television on Sunday.
Even if many people have returned in the meantime: "We should still understand that the war is in a hot phase and Kyiv will remain the main target of the Russian Federation." On Monday night there was another air alert in Kyiv.
On Sunday, the Ukrainian general staff reported several rocket hits in Kyiv.
According to Mayor Vitali Klitschko, one person was injured.
Ukrainian President Volodymyr Zelenskyy said in a video address released in the evening: "Russia's war against Ukraine must be ended as soon as possible." He did not comment on how this should be done.
Russia complains that Ukraine has put negotiations on an end to hostilities on hold.
Ukraine has been fighting the Russian invasion for more than 100 days.
The United Nations has so far registered more than 4,100 civilian deaths, but assumes the number of civilian casualties to be far higher.
Zelenskyj visits embattled Zaporizhia region
During a visit to the embattled region of Zaporizhia on Sunday, Zelenskyi found out about the military situation.
Almost 60 percent of the south-eastern Ukrainian region has been occupied by Moscow's troops since the Russian invasion on February 24, said the region's military governor, Olexander Staruch, during talks with the president in the city of Zaporizhia.
"Many people are arriving from places temporarily occupied by the enemy," Zelenskyy said.
The refugees need housing and jobs.
A particularly large number of people from the embattled eastern Ukraine fled to Zaporizhia, including from the Donetsk region.
There is also the port city of Mariupol, where pro-Russian separatists took control with the help of Moscow's troops in May.
Fighting in Donbass continues.
One focus is the administrative center of Severodonetsk in the Luhansk region, where, according to the authorities, Ukrainian troops are successfully resisting Russian units.Keywords:
