By Andrea Shalal, Thomas Escritt and Tom Balmforth WASHINGTON/BERLIN (Reuters) -U.S. President Donald Trump threatened "severe consequences" if Russia's Vladimir Putin does not agree to peace in Ukraine but also said on Wednesday that a meeting between them could swiftly be followed by a second that would include the leader of Ukraine.

Ukraine lost around 14,000 soldiers and civilians during this period. But in February 2022, Putin launched his full-scale invasion. Russian troops quickly reached the outskirts of Kyiv and seized huge swathes of the south, including big chunks of two more oblasts, Zaporizhzhia and Kherson.
