SANAA- Yemeni police opened fire on protesters in the capital Sanaa on Tuesday, wounding at least 65 people demonstrating for an end to President Ali Abdullah Saleh's 32-year-old rule, hospital sources said.
Six of the wounded were in a serious condition, they said.
Policemen and security agents in civilian clothes opened fire as they tried to prevent people from joining thousands of protesters who have camped out for weeks in front of Sanaa University, witnesses told Reuters earlier.
The state news agency Saba blamed the shooting on gunmen linked to a tribal leader and said three demonstrators and three policemen were injured. It said police were hunting the gunmen. Earlier police brought out water cannon and placed concrete blocks around Sanaa University, after weeks of fierce clashes across the country between government loyalists and protesters that killed at least 27 people.
