Protesters knock down a police barricade near Argentina's National Congress and clash with riot police in the capital, Buenos Aires, during a debate on whether to overturn President Javier Milei's veto of a bill to increase pensions. Milei, a budget-slashing libertarian, blocked an 8.1-percent pensions increase approved by both houses of Congress, which aimed to help cushion retirees in the South American country hit by annual inflation of 250 percent.
