The Nigerian-based terrorist group Boko Haram kidnapped and executed an aid worker who was captured seven months ago in an attack at a military facility.   

Hauwa Liman, 24, was reported dead Monday by Nigerian officials. She, along with two other International Red Cross Society (ICRC) aid workers, was kidnapped by the jihadist militant organization in March. CNN reports she worked in an ICRC displacement camp in the secluded town of Rann just outside of Maiduguri in Borno State.

Militants sent a video appeal to the Red Cross as the 24-hour deadline for a ransom loomed.

“Please show some mercy. Hauwa and Alice went to Rann to save lives and they deserve to live,” the group pleaded with captors. 

According to The Independent, captors reportedly killed the woman for "betraying Islam" by working for the ICRC.

"We have not been able to confirm independently Hauwa's death. We are aware of the media reports that our colleague Hauwa has been executed by her captors, at this stage we cannot confirm if this information is true," Aleksandra Matijevic Mosimann, ICRC spokeswoman in Nigeria, told CNN Tuesday.

"If confirmed, It would be a devastating blow. For the family, Hauwa's friends and colleagues as well as for all the healthcare workers working in northeast Nigeria."

Liman's death comes after a communications breakdown between the Nigerian government and the woman's captors.

''It is very unfortunate that it has come to this," Nigeria's Minister of Information and Culture Alhaji Lai Mohammed said. "Before and after the deadline issued by her abductors, the Federal Government did everything any responsible government should do to save the aid worker."

Liman was the second aid worker to be killed by the terrorist group. Last month, Saifura Hussaini Khorsa, 25, was executed by Boko Haram militants when her ransom was not met. The New York Times reports her murder was recorded, sent to the Red Cross with demands for ransom for Khorsa's release.

However, the Red Cross has stated it does not pay ransom for kidnapped staff and does not negotiate with terrorists, according to Mosimann.

There are an estimated 3,000 aid workers operating in the northeastern part of Nigeria. Many of them work in hostile areas often attacked by suicide bombers and gunmen, reports CNN.
