The UN mission for Mali, Minusma, said in a statement that at least 30 rockets targeted its small camp on the outskirts of Kidal just before daybreak, calling the incident a “complex terrorist attack.”
The dead include one peacekeeper and two civilians, it said.
One of the injured was a boy with shrapnel wounds to his back, a resident of Kidal who did not want to be named told dpa by phone.
The attack came just over 24 hours after gunmen opened fire in a nightclub in Bamako, killing five people. Al Mourabitoun, a group linked to al-Qaeda in the Islamic Maghreb, claimed responsibility.
The poverty-stricken West African nation is recovering from a March 2012 military coup and an Islamist insurgency that prompted France to send troops to its former colony.
