Protesters went to the streets of Buenos Aires on Tuesday to oppose cuts in spending for the development of universities and demand that the government keep education free.
Thousands of people gathered in front of the presidential palace while trying to fit in the square and nearby streets and choose lawns and sidewalks that were not flooded after the rain the day before.
Nearby streets leading to the palace were closed to traffic. A crowd of protesters moved along them from the Congress building, which is a 15-minute walk away.
Such protest actions also took place in other cities across Argentina.
Argentine broadcaster TN reported, citing the University of Buenos Aires, the largest public university in the capital, that some 500,000 students and teachers took to the square in front of the presidential palace to participate in the protest.
Argentine President Javier Milei discredited demonstrators by liking a post on X that read "this is a political march of thieves, corrupt and lazy people," Argentine broadcaster C5N reported.
