Edmonton police cleared a pro-Palestinian encampment at the University of Alberta early Saturday morning, one of several measures authorities have taken in recent days to crack down on campus protesters at sites across the country.

The Edmonton Police Service said it repeatedly gave campus demonstrators notice that they were breaching university policy and provincial trespassing laws. Officers issued a final warning just after 4:30 a.m. and escorted demonstrators from the north campus quad following one last call to leave, said spokesman Scott Pattison.
