Washington, Mar 2 (IANS): The US State Department on Tuesday said that there has been no significant violation of a plan for a cessation of hostilities in Syria in the last 24 hours.

"Over the last 24 hours, we have not been appraised of any claims of any additional violations of any significance," Xinhua quoted State Department spokesman John Kirby as saying.

"We have seen a notable reduction in violence in Syria, and certainly there has been a reduction, there is no doubt about it," Kirby said.

"It is a very fluid environment and we are just going to keep monitoring as closely as we can," Kirby added.

The US and Russia agreed on a plan for a cessation of hostilities in Syria that has begun on February 27.

The cessation of hostilities was largely envisaged in Munich on February 12 during a meeting of the International Syrian Support Group (ISSG), which is co-chaired by the US and Russia.

The group comprises the Arab League, the European Union, the United Nations, and 17 countries including China.

Although violence in Syria has been reduced, Kirby said that the US will remain concerned about "continued reports of violations" of the ceasefire.
