Military chiefs from the United States and a number of European countries on Thursday presented options to their national security advisers for providing security guarantees to Ukraine, officials said.

Secretary of State Marco Rubio told European counterparts Thursday the US will participate in post-war security guarantees for Ukraine but that the Trump administration believes Europe should take the lead,

US and European officials will immediately work on providing Ukraine with robust security guarantees to open a path for a landmark meeting between presidents Vladimir Putin and Volodymyr Zelenskiy, according to people familiar with the matter.
