NAIROBI — Over the past month, aid groups have not had access to people living in the northern Ethiopian region of Tigray due to clashes between the national military and local forces. This has raised alarm over food, medicine, and fuel shortages, and lack of access to populations impacted by the violence.

No supplies have been allowed into the conflict zone and the government cut off communications in the region. Aid groups have not been able to fully account for the safety of their staff.
