05/04/2011 - Security forces and armed men in civilian clothes have opened fire during protests in the city of Taiz in southern Yemen, a day after clashes there killed 15 people, witnesses said.
Hundreds of security troops attacked tens of thousands of protesters, witnesses told the Reuters news agency on Tuesday, adding that plain-clothed policemen were wielding bats and daggers.
They said several people had been hurt, but there was no word yet from medical sources on casualties.
Protesters responded to the attack by hurling rocks at the security forces.
Our special correspondent, reporting from Yemen, quoted the opposition that the ruling party had called on their supporters to rally in Taiz. The supporters marched towards "Liberty Square".
"They tried to enter the square but anti-government protesters stopped them after which clashes ensued. The police then opened fire and lobbed tear gas shells towards the protesters inside the square.
"As events are unfolding, it is strengthening their (the protesters) resolve."
