At least 22 people were arrested by Yemeni security forces in Aden province while they participated in a rally organized by the opposition, the Joint Meeting Parties, JMP.
Protesters in the rally chanted anti-government slogans and urged the ouster of the regime, "We need freedom. Get out!"
Eyewitness said that Yemeni authorities in Aden tightened the measures of security in an attempt to stop protesters from participating in an anti-government rally in Aden.
Yesterday, Yemeni opposition, JMP, called for the day of rage to hold rallies in various Yemeni cities to protest against the ruling party.
Thursday's demonstration came a day after Saleh announced that he would not seek another term in office and would not anoint his son, Ahmed, as his successor, when his term ends in 2013. The move was widely seen as an attempt to prevent the sort of upheavals seen in Egypt and Tunisia.
