- Dissident spokesman: The Syrian military continues "systematic killing spree"
- State newspaper: Security operations are almost over in Harasta
- An opposition group puts the death toll in the 19-month crisis at about 28,000
(CNN) -- A Syrian opposition spokesman lambasted the government's call for dialogue Tuesday, marking yet another stalemate in the country's 19-month deadly conflict.
"No Syrian is willing to sit down with any of these killers in the Syrian government who have been responsible for every single drop of blood that have been shed in Syria," Syrian National Council spokesman George Sabra told CNN from Paris.
"From day one, the regime played the same tune, call(ing) for political solution while ordering mass killing all across the homeland. They keep putting themselves in a political corner ... while their military keeps its systematic killing spree, murdering hundreds of innocent men and women every single day."
At the U.N. General Assembly on Monday, Syrian Foreign Minister Walid Moallem made his call for a dialogue and accused other states of promoting "terrorism" in his country.

Moallem slammed international calls for President Bashar al-Assad to step down, saying such rhetoric amounts to a "blatant interference in the domestic affairs of Syria, and the unity of its people and its sovereignty."

Background
The Syrian conflict broke out in March 2011 after unarmed protesters, inspired by the success of popular uprisings in Egypt and Tunisia, took to the streets demanding political reform.
The movement devolved into an armed conflict after a brutal and continuing crackdown by government forces.
Foreign Minister Moallem spoke Monday to the U.N. General Assembly just days after world leaders painted a grim picture of the conflict.
Syria has dominated much of the General Assembly discussion -- on stage and on the sidelines -- as world leaders struggle to find a way to resolve the war that has left the Security Council hopelessly deadlocked, with China and Russia opposing some of the toughest measures proposed.
The Security Council has been paralyzed by a division over how to halt the killing in Syria. Russia and China have blocked resolutions calling for al-Assad to transfer power and step down, saying the issue should be settled by Syrians.
Germany has slammed the U.N. Security Council for failure to act, and the United States, Britain and France announced they are backing increased support of non-lethal aid to the Syrian opposition.
