Yemen protesters 'hit by tear gas'
Witnesses say thousands of protesters in southern Yemen, who were demanding their president's resignation, have been attacked with tear gas, batons and bullets by police.
Medical officials said at least 200 of the protesters in Taiz were treated for fainting or breathing problems caused by tear gas. They said three protesters suffered minor injuries. The officials spoke on condition of anonymity out of fear of government reprisals.
Witnesses say a large group of women began the demonstration in the main street and that thousands of men joined them after seeing police attack the crowd.
Activist Ghazi al-Samei said the protesters were shouting "our demonstration is peaceful" and calling on President Ali Abdullah Saleh to go.
