An official says militants have attacked a United Nations base in northern Mali, killing at least three people and injuring 30 others.
Olivier Salgado, spokesperson for the UN mission in Mali, said shelling hit the camp in Kidal early on Friday.
Resident Ibrahim Ag Mohamed said that after the explosions UN helicopters were seen in the sky and he could hear the exchange of fire outside the city.
No group has claimed responsibility for the attack, but it bares the marks of Islamic extremist al-Qaeda in the Islamic Maghreb.
The group claimed responsibility for an attack at a UN mission police base on February 5 in Timbuktu that killed a Malian soldier.
The Kidal UN.base was last targeted by mortars on November 28, killing three people.
