Protester killed in new Yemen demo
Protesters in Yemen's southern port city of Aden have set fire to the municipal building and a demonstrator has been killed, witnesses said, as protests stretch into an eighth day.
Hundreds of protesters also demonstrated in the country's second largest city, Taiz, demanding the removal of the president Ali Abdullah Saleh, a key US ally in battling al Qaida.
A call spread by Facebook and Twitter is urging Yemenis to join a series of "One Million People" rallies on a so-called "Friday of Rage" in all Yemeni cities.
Protesters are demanding the ejection of Mr Saleh, who has been in power for 32 years.
In Taiz thousands of government supporters took to the streets ahead of expected afternoon protests.
