UNITED NATIONS, March 16 (Xinhua) -- The UN Security Council on Friday again called for the implementation of its resolution that demands an immediate cease-fire throughout Syria.

"The members of the Security Council reiterated their call for the full implementation of Resolutions 2254 and 2401," said Dutch Ambassador to the United Nations Karel van Oosterom, who serves as president of the Security Council for March.

The council members reaffirmed that Resolution 2401, which demands an immediate cease-fire, applies throughout the whole of Syria, he told reporters after closed-door consultations of the Security Council on the situation in Syria.

They condemned the penetrators of violence in the rebel-held Eastern Ghouta and in the capital city of Damascus, in violation of Resolution 2401, which was adopted on Feb. 24, said van Oosterom.

The council was briefed by Staffan de Mistura, the UN Special Envoy for Syria, via video teleconference.

The council members reiterated their call for "unconditional, unimpeded and sustained humanitarian access" and urged all parties to the conflict to strictly adhere to their obligations under international humanitarian law to protect civilians.

They reminded parties to the conflict that they are obliged to respect international humanitarian law in attacks during UN-listed terrorist groups, he said.

The council members reiterated their full support for the mandate of de Mistura, the special envoy, to establish "without delay" a constitutional committee, which is to be tasked to write a new constitution for Syria, and called on all parties to work with him, said the ambassador.

They reiterated that the Geneva process remains the key path toward a political solution. They urged Syrian parties to participate in negotiations in good faith and encouraged the special envoy to reconvene the Geneva negotiations as soon as possible, van Oosterom said.
