About 400 peace activists demonstrated at the gates of the Minnesota National Guard air base at Minneapolis-St. Paul International Airport, protesting the departure of about 70 Guard members to Panama. The mission is to include deliveries of mail and supplies to U.S. embassies in Central America. Two more trips to Central America involving the Minnesota National Guard are planned for this month. Early in the morning, 22 protesters climbed over an airport fence. They said they hoped to obstruct the planes, but were escorted off the base by security officers. None of the activists was arrested.
