The Arab League on Sunday rejected amendments proposed by Damascus to its proposal to send a 500-strong delegation to monitor the violence in Syria, saying they would radically alter the mission. \"It was agreed that the amendments and appendices proposed by the Syrian side affect the core of the document and would radically change the nature of the mission which is to oversee the implementation of the Arab plan to end the crisis in Syria and protect Syrian civilians,\" the Arab League said in a statement.
