Students protesting higher education reform have sabotaged a Greek state TV news bulletin, bursting into the studio during a live broadcast.
The programme was quickly pulled off the air and the uninvited guests denied the chance to voice their grievances on screen.
On the streets of Athens, silencing angry anti-austerity protesters proved much more difficult. Clashes erupted with riot police in the first such unrest since a lull during the summer. Tear gas was used as security forces blocked demonstrators from accessing parliament.
The protest came as government officials pursue efforts to secure debt-ridden Greece’s latest wad of cash from international lenders to avoid a default.
