According to medics, six are in a serious condition.
Witnesses said security forces fired rubber bullets, teargas and live rounds.Several people are thought to have been shocked by electric stun guns.
The Yemeni protesters, mostly students, have been camped out in front of the university since mid-February. They want Saleh to stand down and an end to corruption.
