Militant students shout slogans as they hold a rally calling for an end to martial law in southern Maguindanao province as they commemorate International Human Rights Day just outside the gates of the Malacanang Presidential Palace in Manila, Philippines, Thursday, Dec. 10, 2009. Critics called it a dangerous precedent, but cabinet members said martial law was needed to stave off a rebellion by the powerful Ampatuan clan, the main suspects in the Nov. 23 killings of 57 people, and their thousands-strong private armies ready to fight the government.
