United Nations envoy Kofi Annan will hold a second meeting with the country's President Bashar Assad on Sunday, March 11 to discuss proposals for stopping violence and starting a political dialogue, a U.N. official in Damascus said, according to AP.

In his talks with Assad on Saturday, Annan made several proposals towards ending the country's yearlong political crisis. He was rebuffed by the president who rejected any immediate negotiations with the opposition, striking a further blow to already staggering international efforts for talks to end the conflict.

Assad told Annan that a political solution is impossible as long as "terrorist groups" threaten the country.

The opposition's political leadership has also rejected dialogue, saying talk is impossible after a crackdown that the U.N. estimates has killed more than 7,500 people. That makes it likely that the conflict will continue to edge toward civil war.

The official said Annan is scheduled to meet with the country's grand mufti, who is a senior cleric, and again with Assad Sunday before heading to the Gulf state of Qatar. He spoke on condition of anonymity in line with regulations.

Meanwhile, activists said fresh violence erupted again in Syria's northern Idlib province, where troops launched Saturday a long-anticipated assault to crush the opposition, bombarding its main city with tank shells from all sides and clashing with rebel fighters struggling to hold back an invasion.

Troops had stormed the village in the northern Jisr al-Shughour area early Sunday and began a campaign of raids and arrests, activists said.
