Citizens of flooded Russian city of Orsk reportedly stage protest
Citizens of Russian city Orsk, which has experienced severe flooding in recent days, protested on Monday against what they view as inaction from local authorities, according to regional news outlet The Moscow Times.
Water levels in Europe's third-longest river, the Ural, which runs through Orsk, have been rising significantly for several days due to melting snow. Two dams in Orsk were said to have burst, allowing parts of the city to flood.
The Russian Ministry of Emergency Situations said on Telegram that thousands of citizens have been evacuated and that the head of the ministry has visited Orsk.
Rescuers were working to rebuild and reinforce dams as water levels in the region and along the Ural river are still expected to rise further, the ministry added.

Russian bank launches 'special military operation' cards for veterans
Russia's state-owned Promsvyazbank on Monday said it had launched "special military operation" bank cards for combat veterans, giving them a form of electronic identification and a simple way to get access to social benefits.
Russia refers to the war in Ukraine as a "special military operation", although the Kremlin said last month that the conflict had "become a war" because of the involvement of the West.
Promsvyazbank offers a range of services but has focused on state employees and the defence sector since it was bailed out by the central bank in 2017. It has opened branches in the four regions of Ukraine that Moscow claimed to have annexed in 2022.
The bank has now started issuing cards in Avdiivka, a town captured by Russia in February, the Donetsk region's pro-Russian information ministry said on Monday.
Promsvyazbank did not immediately respond to a request for comment when asked about Avdiivka.
Russian President Vladimir Putin moved to annex Ukraine's Donetsk, Luhansk, Kherson and Zaporizhzhia regions in September 2022, following what Ukraine said were sham referendums. The move was condemned by many countries as illegal.
Russian forces only partly control the four regions.

Russia, Ukraine trade accusations over power plant strikes, Moscow terror attack
The Russian-controlled Zaporizhzhia nuclear power plant on Monday alleged that a Ukrainian drone was shot down over one of its reactors, a day after Russia accused Ukraine of launching three drone attacks on the plant.
Russia has also accused Ukraine without evidence of facilitating last month's terror attack in Moscow that killed 140 people. Terror group ISIS-K claimed responsibility.
Kyiv denies having anything to do with Sunday's strikes or the terror attack, and on Monday Ukraine's state nuclear energy company accused Moscow of orchestrating a "campaign of provocations."
The head of Ukraine's center for countering disinformation, Lieutenant Andriy Kovalenko, said on Monday that Russia's attempts to blame Ukraine for the terror attack were "propaganda."
"At the same time, Russia is striking the ZNPP with drones, pretending that the threat to the plant and nuclear safety is coming from Ukraine," he added.

UN sounds alarm after strike on Europe's largest nuclear plant
The United Nations' atomic energy watchdog sounded the alarm Sunday after drones struck a nuclear reactor at the Russian-held Zaporizhzhia nuclear plant in southern Ukraine.
The International Atomic Energy Agency said the serious incident "endangered nuclear safety and security" as Europe's largest nuclear plant was directly targeted by military strikes for the first time since November 2022. However, it added that there are no indications of critical damage at this stage.
"This is a major escalation of the nuclear safety and security dangers facing the Zaporizhzhya Nuclear Power Plant. Such reckless attacks significantly increase the risk of a major nuclear accident and must cease immediately," IAEA Director General Grossi said.
Russian nuclear power company Rosatom said Ukraine's military was behind the attack, without providing any evidence. Ukraine has denied any involvement and alleged Russia launched the drones.

"There are air defense systems around the world that can help. Only political will is required to transfer them to Ukraine. I am grateful to the countries that have already helped."
