The Arab League has agreed to ask the United Nations to form a peacekeeping mission and an Arab envoy to attempt to end the bloodshed in Syria, according to media reports.

Arab countries will also suspend all diplomatic relations with Syria, reported Al-Jazeera television.

Saudi Foreign Minister Saud al-Faisal said the Arab League needs to “give all forms of support” to the Syrian opposition and to act accordingly against the government, reported Al-Arabiya.

“How long will we stay as onlookers to what is happening to the brotherly Syrian people, and how much longer will we grant the Syrian regime one period after another so it can commit more massacres against its people?” al-Faisal said, according to the broadcaster.

The Arab League meeting in Cairo on Sunday comes just a week after Russia and China vetoed a resolution in the U.N. Security Council aimed at curbing the violence, which is entering its 11th month. 

However, Syria “completely” rejected the Arab League resolution on Sunday, without giving further details, Al-Arabiya reported.

The U.N. estimates that more than 5,400 people have been killed, but activists say that number is far greater.

Over the past week, activists and human rights groups say the Syrian army has continually attacked the flashpoint city of Homs, killing more than 300. The Local Coordination Committees activist network said on Saturday that 30 people were killed across the country, including 12 in Homs.
