Yemen Police Attack Protesters, One Dead VOA News March 12, 2011 Anti-government protesters carry an injured an injured person into the yard of a Mosque for help following clashes with Yemeni police in Sana'a, Yemen, March 12, 2011 Photo: AP Anti-government protesters carry an injured an injured person into the yard of a Mosque for help following clashes with Yemeni police in Sana'a, Yemen, March 12, 2011 Protesters in Yemen say one person was killed and about 300 were wounded Saturday, when Yemeni police stormed an anti-government sit-in, in the capital, Sana'a. Tens of thousands of anti-government activists had gathered Friday in what was described as one of the biggest demonstrations of its kind to date. The crackdown came despite Yemeni President Ali Abdallah Saleh's promise in a speech Thursday that he would protect demonstrators, whether they were for or against his rule. The president also pledged Thursday to hold a referendum on a new constitution to foster democratic reforms. The opposition rejected the offer, saying it was too little too late. In the southern port of Aden Friday, witnesses said police fired tear gas and warning shots to disperse protesters trying to tear down pictures of Saleh. There were also reports of protests in other parts of Yemen.  Protesters say they are frustrated by rampant corruption and soaring unemployment. Yemen also faces other problems, with water wells drying out and oil resources diminishing. In Washington, a top White House aide called Saleh Friday to say that the U.S. welcomes the president's offers of talks to resolve the political crisis in Yemen. Counterterrorism adviser John Brennan also called on the opposition to work with Saleh. Saleh has been in power since a military coup in 1978 and has said he will not step down until 2013, when his term is due to end. According to Amnesty International, around 30 people have been killed in Yemen since the protests began weeks ago.
