CAIRO - The Arab League has rejected a request by Damascus to amend plans to send a monitoring mission to Syria, where the army has been used to crackdown onprotest against President Bashar al-Assad's rule, Egypt's state news agency reported on Sunday. It said the League rejected Syria's request in a letter from the Secretary-General Nabil el-Arabi to Syria's foreign minister. The League wants to send a 500-strong mission of monitors to Syria to assess the situation there. The League had given Damascus three days from a meeting on Nov. 16 to abide by an Arab plan aimed at ending the violence and starting talks between the government and opposition. The plan included sending a monitoring team to Syria.
