Hundreds of thousands of protesters are flooding the streets across Yemen to demand the ouster of President Ali Abdullah Saleh, while thousands of the embattled leader's supporters are staging counter rallies to celebrate the 33rd anniversary of his rule.
Activist Nouh al-Wafi says demonstrators in the southern city of Taiz on Sunday carried black flags and placards that read "today is the fateful day." Similar protests also were taking place in several other major cities including Amran, Saada and al-Bayda.
In the capital Sanaa, Saleh's supporters raised pictures of the president alongside posters denouncing those seeking to topple him.
Saleh, who took power in 1978, remains in a hospital in Saudi Arabia where he is recovering from wounds sustained in a June 3 attack on his compound.
