Plans for a ceasefire between the Syrian government and rebels fell apart after the government promised Thursday to honor a United Nations-proposed truce to stop fighting over the four-day Eid al-Adha Muslim holiday, according to the Associated Press.
The truce was broken almost immediately after it was supposed to go into effect. Activists within Syria said at least 110 people were killed Sunday, according to CBS News.
This ceasefire attempt is only the latest of proposed truces to fail. No mechanisms to monitor violations were in place, especially for rebel forces.
With an estimated death toll of more than 35,000, the Syrian conflict is the longest and bloodiest trial in the Arab Spring movement.
