The International Committee of the Red Cross (ICRC) has confirmed the death of Hauwa Liman, one of its aid workers in custody of the Islamic State West Africa Province (ISWAP).

The breakaway group of Boko Haram said on Monday it killed the aid worker to show it keeps it words. 

In a statement on the ICRC's website, the group said the death of Hauwa, the second health worker to be killed after she was held hostage by the terrorists for seven months, was "utterly devastating".

It said it received information indicating that Hauwa Liman had been killed by her captors in a despicable act of cruelty.

"The news of Hauwa's death has broken our hearts," said ICRC's Regional Director for Africa, Patricia Danzi.

"We appealed for mercy and an end to such senseless murders.

"How can it be that two female health care workers were killed back-to-back? Nothing can justify this," he added.

Describing the martyred, the ICRC said: "Hauwa, 24, was full of life, becoming a midwife at an early age.

"People who knew her described her as a sociable, dynamic and enthusiastic woman who was much loved by family and friends.

"She was truly dedicated to her work helping vulnerable women in her family's home area.

"Hauwa was abducted in an attack in the north-eastern town of Rann on 01 March, together with Saifura Hussaini Ahmed Khorsa and Alice Loksha.

"Saifura was deliberately killed on 16 September, while Alice remains in captivity, along with Leah Sharibu, a 15-year-old student abducted by the group in a separate incident in February. Hauwa and Saifura worked in a health-care centre supported by the ICRC; Alice worked in a centre supported by UNICEF".

On efforts of the organisation to secure her freedom before she was murdered, the ICRC Regional Director further said the group made sustained and committed efforts to secure the release of the three health-care workers, including a last-minute plea for mercy on Sunday to the Islamic State's West African province group, to no avail.

"Hauwa and Saifura's deaths are not only a tragedy for their families, but they will also be felt by thousands of people in Rann and other conflict-affected areas of north-east Nigeria where accessing health care remains a challenge. We urge the group holding Alice and Leah to release them safely," said Danzi.

Tendencies for crime have been linked to substance abuse and consumption of these substances is increasing in most parts of Nigeria.
