This news from Texas. Hundreds of Pastors for Peace volunteers preparing to deliver a massive shipment of humanitarian aid to Cuba have been barred at the U.S.-Mexico border and could be held there for days. Commerce Department officials are saying they will search every vehicle in the caravan and every item of humanitarian aid, which hasn’t been done for years, and they will only allow what Washington deems “licensable” goods to be allowed to cross into Mexico. Border agents are threatening to tow the caravan’s vehicles and have already seized some aid donations, including computers. Some volunteers are walking across the U.S.-Mexico border carrying wheelchairs, crutches and other medical supplies. Others are holding a protest at the border. There are 130 U.S. citizens traveling with the delegation, as well as a truck and 2 small cars. They are attempting to deliver 140 tons of aid. The Bush Administration tightened restrictions against Cuba in 2004, and is using Homeland Security funds to investigate those suspected of travel to the island.
