Syria stressed on Monday its rejection to a fresh Arab proposal of joint Arab-UN forces to Syria, regarding the move as "a blatant interference and an encroachment upon its national sovereignty," the state-run SANA news agency quoted an unnamed official as saying.

A day earlier, the 22-member Arab League (AL) announced it had formally ended its observer mission to Syria, which was suspended last month.

In addiction to opening communication channels with the Syrian opposition, the bloc's members also decided to ask the UN Security Council to mull on joint UN-Arab peacekeeping forces to oversee the implementation of a ceasefire.

The official said the AL decision contained "slanders and fallacies" that are totally irrelevant to what is happening on the ground.

He called the decision a move aiming to renew the conspiracy by some Arab countries, which attempt to pre-empt the role of the AL in resolving the Syrian crisis and to internationalize the Syrian issue.

The official went on to say this decision, however, "won't dissuade Syria from bearing its responsibilities of protecting the civilians and maintaining security and stability."

Syrians have been expecting the AL chief and other Arab ministers to declare a clear-cut denunciation on the terrorist acts in the capital Damascus and Aleppo as well as to halt their media provocation and all kinds of support to those terrorists, the official said.

A day earlier, Syria's ambassador to Cairo echoed his country's rejection to the AL decision, saying it reflected "hysteria" among some of the Bloc's members after they failed to secure a UN Security Council's intervention.

Meanwhile, Syria's official papers launched vitriolic criticism Monday against the AL's fresh calls.

The Tishrin newspaper said in an editorial that the AL has clearly called on all Arab countries to support the opposition "to cling fast to its stand of rejecting dialogue and expanding areas of field escalation."
