Gunmen have taken 170 people hostage inside the Radisson Blu Hotel in Mali's capital, Bamako.
The hotel chain said two armed men have locked in 140 guests and 30 employees.
Malian soldiers with help from U.N. troops have the hotel surrounded.
No group immediately claimed responsibility for the incident.
"This week there was a big delegation for the peace process at the Radisson hotel in Bamako," said Olivier Saldago, a spokesman for MINUSMA. MINUSMA is the U.N. mission in the nation.
The United Nations sent peacekeepers to Mali in 2013 to guard against militant Islamists who threatened to move on Bamako.
The U.S. Embassy in Mali asked American citizens and its staffers to remain indoors. The embassy, in a tweet, called it an "ongoing active shooter operation."
