Secretary Clinton said the US supports Joint Special Envoy for Syria Lakhdar Brahimi's call for a ceasefire for Eid al-Adha. Clinton said again what she has said repeatedly in the past that the US would like to see the violence come to an end, and see a political transition begin.
Clinton also condemned the attack in Lebanon that killed the head of their intelligence agency. She said she spoke with the Lebanese Prime Minister over the weekend and expressed her condolences. An FBI team will support the Lebanese investigation into the bombing.
"We don't want to see a vacuum of legitimate political authority that could then be taken advantage of by the Syrians or by others that could create even greater instability and violence.
"So we call on all parties in Lebanon to support the process that President Suleiman is leading to choose a responsible, effective government that can address the threats that Syria faces and hold accountable those responsible for last week's bombing."
Dozens of people were killed at dawn in Douma city to the northeast of the capital Damascus, with both the government and the rebels accusing each other of the massacre.
The state-run SANA News Agency said that an "armed terrorist group has committed an ugly massacre that claimed the lives of 25 people who were killed by knives near Hawa Mosquein Sli Bin Taleb Street in Douma."
The opposition accused the Syrian government of being behind the “massacre".
The United Nations-Arab League envoy to Syria Lakhdar Brahimi announced the Syrian government and some rebel leaders had agreed to a ceasefire during the upcoming Muslim holiday of Eid.
Announcing the first truce in the 19-month conflict that has claimed the lives of more than 34,000 Brahimi said the truce could be something to build upon:
"The government have agreed to a truce during the Eid al-Adha holiday...The majority of some rebel leaders which we were able to establish contact with have also agreed to a truce if this initiative succeed and hold we will be able to build on dialogue for a longer cease fire"
The Syrian foreign ministry has said its army are still studying the terms of Lakhdar Brahimi's truce proposal and will announce their decision on a temporary ceasefire to mark the Eid holiday shortly.
The Muslim holiday of Eid is due to start tomorrow and lasts three of four days. Brahimi said some of rebel groups had also agreed, in principle, to a truce. Brahimi said:
"After the visit I made to Damascus, there is agreement from the Syrian government for a ceasefire during the Eid."
