Nine UN peacekeepers from Niger have been killed when their convoy was ambushed in north-east Mali.
The UN said it was the deadliest attack on its mission in Mali.
French and African troops intervened in Mali in January 2013 to stop the southern advance of Islamist militants on the capital, Bamako.
The insurgents were expelled from the northern towns they controlled but attacks have continued against the UN force deployed to help bring stability.
The 9,000-strong UN force, known as Minusma, took over peacekeeping operations in July 2013.
