A number of foreign rescue teams have also arrived and their presence is making a difference. Members of the UK-based charity, International Rescue Corps, have used life-detecting sensors to locate a thirteen-year-old boy from under the rubble. They are now searching for more survivors. Rescue teams from Turkey are also involved in similar work. But with thousands already dead, many here have been highly critical of the government's relief efforts and say it's too little, too late.
