ABUJA, Nigeria — Boko Haram militants have killed at least 11 people, including three aid workers, in an attack on a military base near a camp for displaced people in the northeastern state of Borno in Nigeria, according to the United Nations migration agency.

The raid Thursday night in the town of Rann, near the border with Cameroon, was the latest high-profile attack by militants in Nigeria’s northeast, and it comes less than two weeks after the abduction of 110 girls from a school in the town of Dapchi in neighboring Yobe State.

The United Nations agency, the International Organization for Migration, said the attack had been carried out by militants using automatic weapons, rocket-propelled grenades and gun trucks. The three aid workers who were killed were all Nigerian, the agency said.

Four soldiers and four police officers were also killed in the attack, the agency said, with three other humanitarian workers wounded.
