Mali plans to boost security measures after al-Qaeda-linked gunmen killed at least 20 people at a luxury hotel in the capital, highlighting risks in a country facing an Islamist rebellion.

President Ibrahim Boubacar Keita and his cabinet at an extraordinary meeting late Friday vowed to reinforce security, state television reported, without providing more details. They met after Malian troops ended an about 10-hour siege by gunmen at the Radisson Blu Hotel in Bamako. At least two of the gunmen also died.

The attack began on Friday morning when gunmen burst into the lobby spraying gunfire. Hours later, troops stormed the hotel and moved room to room evacuating guests, while French and U.S. security forces aided the operation.

As many as 170 people had been trapped inside the hotel and at least 105 of them were rescued, according to state television. One of those killed was an American citizen, the U.S. State Department said without providing additional details.
