Update: 11 killed, including 3 UN workers, in Boko Haram attack

At a UN briefing in Geneva, IOM spokesman Joel Millman said two members of staff, Ibrahim Lawan and Yawe Emmanuel, were among three humanitarian workers killed along with eight members of police and the military.

The UN's humanitarian aid co-ordinating agency, OCHA, said a third aid worker killed was a medical doctor consulting for Unicef.

IOM director of operations and Emergencies Mohammed Abdiker said the agency was "outraged and saddened" by the killings.

The two IOM workers were contractors working in a camp for 55,000 internally displaced people who have fled conflict in the region.

UN officials said the humanitarian crisis in north-eastern Nigeria is one of the worst in the world, with more than 7.5 million people in need of assistance.

Some 3,000 aid workers with the world body, its agencies and NGOs are providing aid to some 6.1 million people in the region.

We firmly condemn the attack that has taken the lives of our colleagues in Nigeria.
