Russia vetoed a UN Security Council resolution on Monday calling for an immediate end to hostilities in Sudan where a war between two rival generals has been raging since April 2023.

A draft of the resolution prepared by Britain and Sierra Leone, which was seen by AFP, had called on both sides to “immediately cease hostilities” and begin talks on “a national ceasefire.”

“One country stood in the way of the council speaking with one voice. One country is the blocker,” British Foreign Secretary David Lammy said after the vote, which showed 14 countries in favor and only Russia against.

During previous votes on Sudan in the Security Council, Russia had abstained.

The UN has been largely paralyzed in its ability to deal with conflicts from Ukraine to Gaza because of splits between permanent Security Council members, notably Russia and the United States.
