UN Secretary General Kofi Annan addressed the Russian president with a corresponding request. In January 2005, an agreement was signed in Sudan to end the civil war that had lasted 21 years. But in the Darfur province in the west of the country, an armed conflict is still ongoing, killing tens of thousands of people. The UN Security Council has repeatedly threatened Sudan with sanctions, demanding that the militants be disarmed. In turn, the Sudanese government accuses the UN of interfering in its internal affairs.
