MOSCOW, Feb 24 (Reuters) - Russia accused Ukraine on Tuesday of trying to obtain a nuclear weapon with help from Britain and France, an allegation Kyiv called an absurd lie. A French foreign ministry spokesperson said the allegation was "blatant disinformation".

Russia is increasingly reliant on foreign fighters from around the world to prosecute its war in Ukraine, writes

Four years of war in Ukraine has brought seismic evolution to the world - to the nature of warfare, the balance of global powers, and to European security.

By Andrea Shalal WASHINGTON, Feb 24 (Reuters) - The Ukrainian government received a formal, official message from the U.S. State Department recently after attacks by Ukraine on the Russian port of Novorossiysk affected U.

Among the most difficult points are the fate of Ukraine's partially occupied eastern Donbas region and the nature of post-war Western security guarantees for Ukraine.

South Africa's President Cyril Ramaphosa said 11 men who were allegedly tricked into fighting for Russia in the war in Ukraine are being sent home.

Four years of war have discouraged Ukrainian and Russian women from having children, and that could impact their economies in the future.

Our model suggests that Russian casualties are now between 1.1m and 1.4m, of whom 230,000-430,000 are dead. That would mean one in 25 Russian men between the ages of 18 and 49 may have been killed or severely wounded since the start of the full-scale war.
