TORONTO (AP) — A spokeswoman for U.S. pastor Terry Jones said Thursday that Canada has denied entry to the preacher, whose congregation held a Quran burning in March 2011 that triggered deadly protests in Afghanistan.

Stephanie Sapp said fellow pastor and her husband Wayne Sapp, along with Jones, were turned back at the Michigan-Ontario border after being detained for several hours. Jones, who leads Florida’s tiny Dove World Outreach Center, and Wayne Sapp, were scheduled to attend Freedom Showdown, an inter-faith debate Thursday evening outside the Ontario Legislature.
