President Trump spent Monday in Helsinki, Finland, for a closely watched summit meeting with President Vladimir V. Putin of Russia, the final leg of a weeklong trip that also took him to Brussels for a NATO gathering, and to Britain for talks with Prime Minister Theresa May and tea with Queen Elizabeth II.

Doug Mills, a New York Times staff photographer based in Washington, is among the photographers traveling with the president.

Here are some of their best images from the trip so far.
