Argentine officers from the National Gendarmerie (military police) sing the national anthem during a nationwide protest outside their headquarters in Buenos Aires October 4, 2012. Argentina fired its chief coast guard and military police officials yesterday after an unprecedented three-day protest by rank-and-file officers demanding better wages. Pay strikes are common in Argentina, where inflation is more than 20 percent annually, according to private economists. But this was the first time in memory that uniformed Argentine military forces have protested over wages.
