More than 1,000 residents of Prague returned to the flood-ravaged neighbourhood of Karlin this week, the first time they had been allowed back to their homes. Some have been allowed home permanently, others were given a few hours to collect valuables and throw out rotting food. Officials say contaminated rubbish and decaying meat in butchers' shops poses a major health hazard. So far, three buildings in Karlin have collapsed, although no one was hurt. Prague authorities have warned they would not be responsible for the safety of residents who violate evacuation orders.
