Reuters takes us to Taiz, where "the daily rhythms of Yemen's main industrial center" are at a standstill. "Dozens of protesters were wounded by gunfire, tear gas and beatings by bat-wielding plainclothes security men," the news outlet reports, and protesters responded by lighting a police building on fire, storming government buildings, and burning tires (see above). The AFP adds that demonstrators locked the gates of the Yemen Petroleum Company with chains and posted a sign: "Shut by the people." This video, via NPR's Andy Carvin, allegedly shows the protesters seizing the police station:
Another video from Taiz highlighted by Carvin seems to capture security forces firing heavy weapons from trucks:
As a Gulf Cooperation Council plan for Yemeni President Ali Abdullah Saleh to step down within 30 days flounders, Reuters points out that the country is simultaneously grappling with a mounting fuel crisis. Tribesman who support the protesters have blockaded Yemen's primary oil- and gas-producing Maarib province, forcing the government to turn to Saudi Arabia for crude oil. The country's currency is plummeting as the prices of necessities soar and remote areas experience water shortages. These crises, coupled with the mounting violence, are creating an increasingly dangerous situation in a fragmented, impoverished country in which, as Reuters points out, "half the population owns a gun." Meanwhile, Yemen-based Al-Qaeda in the Arabian Peninsula warned today that, in the wake of Osama bin Laden's death, the "ember of jihad is brighter," according to AFP.
Update: NPR's Andy Carvin has a steady stream of amateur videos out of Yemen. This one shows people running en masse from gunfire:
