Sep 26, 2006 — President Bush is welcoming Afghan President Hamid Karzai to the White House today. Karzai was in Ottawa last week, surprising organizers of a support-the-troops rally on Parliament Hill Friday. Canadian troops are now leading the peacekeeping mission amid rising violence in Afganistan. The latest bombings there killed at least 20 people today. On Friday, thousands of Canadians turned out in red as a show of moral support for the soldiers and their families. Lucy Martin was there.
