Arab League Secretary General Nabil Al-Arabi said on Saturday that he has sent a letter to the United Nations Security Council, urging it to take "all necessary measures to protect the Syrian people." "I urge you to move quickly to end all acts of violence taking place in Syria, and to take the necessary measures to protect Syrian civilians, including increasing the number of international monitors and allowing them the necessary powers to stop the violations and crimes being committed," Al-Arabi was quoted as saying by Qatari News Agency (QNA). Al-Arabi is in Qatar to attend the meeting of the ministerial committee on the Syrian crisis in Doha, which began its session this morning.
