The United Nations Security Council will vote Friday to call on Rwanda's military to stop supporting the M23 rebel group in the eastern Democratic Republic of Congo and immediately withdraw all troops from Congolese territory "without preconditions."

The M23 has captured the two largest cities in eastern Congo and stoked fears of a wider war. Rwanda denies allegations from Congo and the U.N. that it supports the M23 with arms and troops. It says it is defending itself against Hutu militias which it accuses of fighting alongside the Congolese military.

The French-drafted U.N. resolution "strongly condemns the ongoing offensive and advances of the M23 in North-Kivu and South Kivu with the support of Rwanda Defense Forces (RDF)" and demands that M23 immediately stop its hostilities and withdraw.

A council resolution needs at least nine votes in favor and no vetoes by the United States, Russia, China, Britain or France to be adopted. Several diplomats said it is expected to pass.

Congo says Rwanda has used the M23 rebels as a proxy to loot its minerals such as gold and coltan, used in smartphones and computers. The U.S. has imposed sanctions on a Rwandan minister and a senior rebel for their alleged role in the conflict.

The text also condemns support by Congolese troops "to specific armed groups, in particular the FDLR [Democratic Forces for the Liberation of Rwanda], and calls for the cessation of such support and for the urgent implementation of commitments to neutralize the group."

Rwanda accuses Congo of fighting alongside the FDLR. The Congolese military has vowed to arrest soldiers who cooperate with the FDLR, but the government has continued to use FDLR fighters as proxies, U.N. experts said in December.

The M23 vows to defend Tutsi interests, particularly against ethnic Hutu militias such as the FDLR. The FDLR was founded by Hutus who fled Rwanda after participating in the 1994 genocide that killed close to 1 million Tutsis and moderate Hutus.

The U.N. draft resolution urges the DRC and Rwanda to return to diplomatic talks to achieve a lasting peaceful resolution.

The escalation of a decade-old insurgency has killed several peacekeepers with the U.N. force in Congo, known as MONUSCO.

The draft U.N. resolution warns that "attacks against peacekeepers may constitute war crimes and that planning, directing, sponsoring or participating in attacks against MONUSCO peacekeepers constitutes a basis for sanctions."
