Four journalists are recovering from injuries sustained when masked protesters attacked them after a window-smashing march through Mexico City.

The protesters had joined a larger march honoring students killed in government repression of a 1971 demonstration.

The youths broke windows at bus stops, stores and the ruling party headquarters Tuesday before turning on journalists.

The press freedom group Article 19 said four journalists were hurt, though none of the injuries was life-threatening.

A freelance photographer on assignment for the Associated Press, Marco Ugarte, suffered fractured facial bones. Also injured were Paris Martinez of Animal Politico, Luis Castillo of the Reforma newspaper and freelancer Nestor Negrete.

The Mexico City police department said police kept their distance to avoid provocations and said that "not one single representative of the media was injured."
