A "complex and unpredictable security situation" in Tigray continues to impede the delivery of life-saving assistance to Ethiopia's northern region, the Deputy UN Spokesperson told journalists on Thursday.

Nearly six months since the conflict between Ethiopian Government security forces and regional forces of the Tigray People's Liberation Front (TPLF) began in early November, most rural areas have remained cut off from communications and electricity, impacting access to health services, water supply and vital assistance, said Farhan Haq.
