Syria says any attempt to deliver humanitarian aid to rebel-controlled areas without government approval is tantamount to an "attack on the Syrian state and on its territorial integrity and political independence."

Syria's U.N. Ambassador Bashar Ja'afari sent a letter to Secretary-General Ban Ki-moon and the Security Council from Syrian and Arab lawyers protesting against a draft U.N. resolution that would authorize the delivery of humanitarian aid into Syria through four border crossings without approval from President Bashar Assad's government.

"The sole purpose of the initiative is to use United Nations auspices for the delivery of logistical backing to the terrorists," the letter says.

Syria calls all opposition groups "terrorists."

The letter, obtained Friday by The Associated Press, said humanitarian aid must be delivered with the agreement of the government.
