'Some sort of pattern' in downed objects -Trudeau

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