A US Embassy spokesman says plans have been canceled to try to dock a military ship carrying humanitarian aid in the Georgian port of Poti, where Russian forces are posted on the outskirts. The ship, the Coast Guard cutter Dallas, was to have come to the Black Sea port on Wednesday morning. But embassy spokesman Stephen Guice said the vessel instead will dock in Batumi, a port well south of the zone of fighting in this month's clash between Russia and Georgia. Guice said he did not have information on why the plan was changed. Poti's port reportedly suffered heavy damage from the Russian military. In addition, Russian troops have established checkpoints on the northern approach to the city and a U.S. ship docking there could have been seen as a direct challenge.
