Clashes outside Argentine Congress after veto of pension rise

There have been fierce clashes between protesters and police in Buenos Aires, after thousands of people gathered outside Argentina's Congress to demonstrate against the president's veto of a rise in pensions.

Video shows protesters, many of them pensioners, tearing down fences and entering the Congress area, before officers fired pepper spray and rubber bullets in an attempt to disperse the crowd.

Politicians supporting the pension rise failed to win the two-thirds majority needed to override President Javier Milei's veto.

Milei is trying to pass a series of austerity measures to overturn years of high inflation and public debt in Argentina. He has defended harsh fiscal measures as necessary to fix the economy.
