Police moved in on Monday morning to clear a rail blockade by an indigenous group in eastern Canada that had been stopping freight and passenger traffic for more than two weeks on one of the country's busiest lines.

Canadian National Railway Co. obtained an injunction against those preventing rail traffic from running along its trunk line near Belleville, Ontario, on Feb. 7, but provincial police had taken a cautious approach until now.

Dozens of Ontario Provincial Police (OPP) descended on the site of the blockade a little after 8 a.m. ET. The Canadian Broadcasting Corp. said there had been about 10 arrests so far.
