In Yemen, thousands of people are demonstrating against President Ali Abdullah Saleh in the capital Sana’a today for the second time in less than a week. The demonstrations appear to be the largest ever to directly oppose Saleh’s three-decade leadership. Like Mubarak, Saleh has been a critical U.S. ally in the Middle East. Classified U.S. Department of State cables released by WikiLeaks show the United States and Saleh have covered up the use of U.S. warplanes to bomb Yemen.
