Yemeni President Ali Abdullah Saleh remains in Saudi Arabia seeking medical treatment four days after he was injured in an attack on his presidential compound. Yemen’s acting leader says Saleh would return in days, but there is growing pressure for Saleh to step down from power. U.S. Secretary of State Hillary Clinton called for an immediate transition of power. Meanwhile, new reports suggest Saleh may have been far more seriously injured than acknowledged. U.S. officials say Saleh suffered burns on 40 percent of his body and a collapsed lung.
