Tensions continue to mount in Yemen as anti-government protests entered their six consecutive day on Wednesday.
The demonstrations calling for President Ali Abdullah Saleh to resign are spreading across the country.
In the southern port of Aden, 500 protesters turned on police who fired into the air to disperse the crowd. One man died in the clashes.
The epicentre of the unrest has been the capital, Sanaa.On Wednesday, hundreds of students led a rally calling for the ouster of Saleh, in power for 32 years. However, it turned violent when armed government supporters arrived on the scene, chanting pro-Saleh slogans.
The 64-year-old head of state has already promised to step down when his current seven-year term expires in 2013. But that has failed to appease the protesters, who want Saleh to go now.
