Shortly after becoming president, Aquino ordered the release of hundreds of political prisoners imprisoned during the Marcos era, including communist insurgents belonging to the Communist Party of the Philippines. These releases included leaders such as Communist Party of the Philippines founder Jose Maria Sison and New People's Army founder Bernabe Buscayno. Preliminary peace talks with the CPP ended after the Mendiola Massacre on 22 January 1987, which had allegedly included New People's Army members amongst the 12 killed.
