Russia vetoed a Council resolution for security for the conflict in Sudan, reported Reuters, quoted by BTA..
All of the other 14 member states of the Council, including China, backed the measure proposed by Britain and Sierra Leone in yesterday's vote.
The text called on the parties to the Sudanese conflict to immediately cease fire and ensure the delivery of humanitarian aid.
British Foreign Secretary David Lammy, whose country holds the rotating presidency of the Security Council this month, condemned the "petty, dirty and cynical" a Russian move that he says sends a message to warring parties that they can act with impunity.
However, the veto imposed by Russia was welcomed by the Sudanese Ministry of Foreign Affairs, which is linked to the regular army, as support for the sovereignty and unity of the country, as well as international law.
A quick solution to the conflict is needed, and the only way to achieve it is a ceasefire, said Russian Deputy Permanent Representative to the UN Dmitry Polyansky. At the same time, he accused the draft resolution's supporters of "double standards" in giving Israel carte blanche to continue violations of international humanitarian law in Gaza, and described Lammy's criticism as "an excellent demonstration of British neo-colonialism".
The conflict in Sudan, which erupted in April last year, pits the regular army against the paramilitary Rapid Support Force. It led to the world's worst displacement crisis, notes Reuters.
More than 25 million people - half of Sudan's population - are in need of aid, according to the United Nations, with famine looming in refugee camps. Over 11 million people have left their homes, with more than 3 million of these people going to other countries.
Meanwhile, the US special envoy for Sudan, Tom Perriello, arrived yesterday on his first visit to the country, Reuters reported.
He met in the port city of Port Sudan, the de facto capital of the regular army-held areas, with its commander, Abdel Fattah al-Burhan.
Perriello, who was appointed to the post in February, called for an increase in humanitarian aid deliveries and an end to the devastating conflict.
At the meeting, calls were made to increase aid to the Gaza Strip, Reuters reported.
The situation in the Palestinian territory is worsening, the speakers warned, at a time when, according to unverified data from local authorities controlled by the Islamist movement "Hamas", the number of people killed in the Israeli military operation is approaching 44 thousand. Most of Gaza's 2.3 million residents have been forced from their homes since the war began more than 13 months ago.
British Foreign Secretary David Lammy, who chaired yesterday's meeting, called for a "huge, huge increase in aid" for the coastal Palestinian territory. "The situation is terrible and, frankly, incomprehensible, and it's getting worse, not better," he warned.
US Permanent Representative to the UN Linda Thomas-Greenfield made it clear that Washington is closely monitoring Israel's efforts to improve the situation for the Palestinians and is in daily contact with the Israeli government.
On October 13, the United States gave Israel a deadline of 30 days to improve the humanitarian situation in the Gaza Strip, warning that otherwise it may reduce its military aid to it, Reuters recalls.
Israel is working on implementing 12 of the 15 measures that Washington is pushing for, Thomas-Greenfield reported at the meeting.
The war broke out on October 7 last year when fighters of "Hamas" and other Palestinian groups invaded Israel, where they killed about 1,200 people and took over 250 hostages and took them to Gaza.
