Justin Trudeau has been hit by a handful of gravel as anti-vaccination protesters targeted the Canadian prime minister's campaign for re-election.

A CTV camera captured what appears to be white gravel hitting Trudeau and one of his bodyguards as he walked toward his campaign bus in London, Ontario. The Liberals cancelled an event late last month because of safety concerns linked to anti-vax protesters.
