'Some sort of pattern' in downed objects -Trudeau

Canadian Prime Minister Justin Trudeau said on Monday that
the four aerial objects shot down in recent days, including one
Over Yukon territory on Saturday, are connected in some way,
without elaborating. White House national security spokesman
John Kirby told reporters in Washington that there was one
similarity: "these objects were not being maneuvered. They did
not appear to have any self-propulsion."
