UN base attacked in northern Mali

Two United Nations peacekeepers in Mali have been killed in an attack on one of their bases in Kidal, in the north of the country. 

Thirty other blue helmets were injured in the raid, and a plane destroyed by mortar fire. 

A UN spokesman said reinforcements had been summoned from other bases in the region and the attackers driven off. 

The UN is trying to restore peace to northern Mali, which was overrun in 2012 by Islamist extremists and their allies, Tuareg separatists. 

But it's one of the most dangerous peacekeeping missions in the world, with the UN coming under frequent attack.

UN soldiers have been helping to boost security in Mali since 2013
