• Russia's defense ministry says it has destroyed two unmanned Ukrainian boats, which it claims were attacking one of its fleet patrol ships in the Black Sea. There were no casualties reported in the operation which Moscow says was carried out using "standard weapons of the Russian ship at a distance of 1000m and 800m."

• Two people, including a 10-year-old boy, are reported killed in a Russian attack on the eastern city of Kostiantynivka. The governor of the Donetsk Oblast says seven others were also wounded in what's believed to be a shelling carried out with the use of cluster munitions. 

• The Kremlin has accused Kyiv of carrying out a "deliberate attack on journalists" following a strike on Saturday in Ukraine's southeastern Zaporizhzhia region that left a reporter dead. Moscow says a criminal investigation has been launched into the death of Rostislav Zhuravlev, who worked for Russia's state news agency RIA. 

• Meanwhile, the UN's nuclear watchdog says anti-personnel mines have been seen at the site of Ukraine's Zaporizhzhia nuclear power plant, which is occupied by Russian troops. IAEA chief Rafael Grossi says his team saw "mines located in a buffer zone between the site's internal and external perimeter barriers" while on a trip to Zaporizhzhia at the weekend.

Kyiv mayor calls for more support

Kyiv's mayor has appealed for more targeted military support to defend Ukraine's capital, after the sixth night of strikes this month.  In a post on Telegram, Vitali Klitschko said that what he called a "coordination council" is needed, made up of local representatives along with Ukraine's Ministry of Defense, to decide on hardware issues.

"We need to understand the real needs, what exactly needs to be purchased. Not general drones. Which ones, to whom, and in what quantity?" said Klitschko. "Drones are not a panacea. Our defenders still need a lot of things, starting with anti-drone protection equipment, for example."

There were no casualties reported after the latest overnight attack on Kyiv on Monday. Sirens began at around 1.40 a.m. local time and lasted for three hours. 

Ukraine says the Iranian Saheed drones launched on the city were intercepted. Sergiy Popko, head of the Kyiv city military administration said on Telegram, "All air targets were detected and destroyed on the approach to Kyiv." 

Meanwhile, Ukraine's Air Force says drones were also dropped in three regions in the north of the country. Infrastructure was damaged around the city of Zhytomyr, 140K west of Kyiv, while an empty aircraft hangar was damaged in the central region of Cherkasy. 

Ukraine's military chiefs have also issued air raid warnings for the east and southeast regions of the country, saying the use of ballistic weapons by Russian troops is increasingly likely.
