At least 32 people were killed in the September demonstrations
The International Crisis Group (ICG) think-tank has called for forceful international diplomacy to put the electoral process back on track in the Democratic Republic of Congo.
Their panel of experts says street protests have become the main form of political expression in the country.
At least 32 people died last month when protests against President Joseph Kabila were violently put down.
The International Crisis Group warns urban violence could now spread beyond Kinshasa.
The group’s briefing paper calls for targeted sanctions against leaders who inflame tensions, and suggests threatening to withdraw UN peacekeepers from eastern DR Congo.
President Kabila took over from his father in 2001. He is due to finish his term at the end of this year. But presidential elections due in November have been delayed.
