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, APA reports citing Reuters.
A Pentagon statement said U.S. and European planners had developed the military options for "appropriate consideration" by allied national security advisers. Reuters was first to report that the military leaders were preparing the options.
The chiefs of defense for the United States, Finland, France, Germany, Italy, the United Kingdom and Ukraine met in Washington, D.C., between Tuesday and Thursday.
A source familiar with the matter said U.S. Secretary of State Marco Rubio, who also serves as Trump's national security adviser, held a conference call on Thursday with his European counterparts to discuss the options.
"The planning work continues," said the source, adding that Washington still was "determining the scope of its role."
Trump has said he will not deploy U.S. troops in Ukraine but has left the door open to other U.S. military involvement, including air support.
