Demonstrators and police clash during protests outside Congress in Buenos Aires, where groups of retirees have been demanding better pension conditions every Wednesday for the past eight years. Several of the hundreds of demonstrators, tear-gassed and beaten by riot police, are arrested, and others lightly injured. Argentine President Javier Milei's fiscal adjustment, designed to stabilize the economy, hit the country's more than 7 million retirees and pensioners the hardest, freezing their incomes and subsidizing their medicine. He also vetoed a law that would have given them an 8% increase. IMAGES AND SOUNDBITES [TO COMPLETE 36YQ8VB_EN]
