A twin bombing that killed 58 people at a camp in a northeastern Nigerian town last week underlies the destructive capacity of Boko Haram that’s left 3 million people cut off from access to aid two months after President Muhammadu Buhari said the Islamist militant group had been defeated, Bloomberg reports.

The camp at Dikwa stands in a town where shops and homes have been deserted by residents who fled Boko Haram’s onslaught, before it was liberated in July. About 53,000 displaced people live in tents pitched on an expanse of arid land guarded by soldiers in an area about 89 kilometers (55 miles) from the Borno state capital of Maiduguri. They’re among those who can’t be reached by aid organizations from United Nations to U.K-based Oxfam, who won’t venture there due to security concerns.

Buhari said in December that Nigerians displaced by the violence would be returned home this year and that Boko Haram had been “technically defeated”. Despite boosting defense spending last year, his administration hasn’t presented a clear plan to redevelop the northeast at a time when government finances are pressured by a 46 percent plunge in the price of Brent crude in the past year, with oil providing about two-thirds of revenue. Borno, the worst hit state, needs more than $1 billion to repair damage done by the insurgency.

“I have spent two days without food,” said Baana Masa, a 56-year widower in Dikwa who lines up everyday with his two children hoping their turn comes before the food runs out. “We escaped Boko Haram’s manhunt and now we are facing hunger.”

As attacks continue in the northeast, Maiduguri, home to about two-thirds of 2.2 million displaced people in accessible zones, and Yola, the capital of neighboring Adamawa state, remain some of the few places with the minimum level of safety required for international aid workers to operate, Bloomberg says.
