AT LEAST 75 people were injured on Monday when a mezzanine floor in Indonesia's stock exchange building collapsed into the lobby, police said, with victims carried out of the debris-filled building on stretchers.

Dramatic CCTV footage showed a group of some 40 visiting students on a balcony section plunging as the floor gave way with a cascade of glass, metal and other material crashing onto the ground floor where several other people were walking.
